[Detailed description of the invention]

Increasing the bit speed of optical data streams Background of the invention 1. field of invention The present invention focuses on the technology of transmitting an optical data stream over an optical path. 2. Prior art theory Akira In the past few years, fiber-optic communications has gained a lot of attention, including improvements in the distance that can be transmitted without the use of intermediate equipment, as well as Significant progress has been made in increasing the speed of data that can be transmitted. inside optical fiber The dispersion of color at any distance i! A large data rate transmitted through fiber between It is known that it has a very large influence on Furthermore, medium difficulty and medium! ! with the vessel The long-distance irises in question also have temporal indistinctness in the transmitted number 1 rather than the optical loss of 8 shoulders within the fiber. It is greatly constrained by the color dispersion within the phaino, which causes the shading. The wavelength at which the chromatic dispersion in the fiber is minimal, typically about 1.3 Pulse distortion can be minimized by operating at 2 & can. Also, by using a light source with a very narrow color spectrum, we can Dispersion can be minimized, especially at wavelengths other than the dispersion wavelength. It is effective when it works. gAeζ, most silica optical fibers are about 1.55 Although there is a slight loss in the length of the microphone mouth, it is required to operate at this length. It will be done. In short, we adopt a Kansaku Dingou-mode source fiber in the zero dispersion direction. 11!1, as well as using a light source with a very narrow spectrum. Improvements have been made in the distance between questions and the speed of data. However, to the point of strain Assuming that we use a completely perfect optical fiber, and essentially a red light beam, Even if there is a large charge or T# presence in the distance of data transmitted through the destination fiber. Slow. This constraint is one

[; Rez or other light source is turned off and turned off. This is due to the degree of change, that is, the degree of modulation. In some cases, this constraint is due to the physics of the light source itself, which requires some time between the application of the feedback pulse and the generation of the first pulse. In addition, the electric pulse From the time the light pulse reaches Xa's value, until it reaches zero value, there is a mechanical Atsunori. Other constraints include the cabacic (mata) and a) guktance in the summer vessel, which restricts the electrical response sound within the vessel.It preserves the storm-like characteristics of the light source. Due to the necessity of Yes, but it requires two more hires. This is a moat of nine ministers. Optical fibers can produce light beams of several gigahits/second (i.e., more than 109 hits/second). This is because it is possible to send messages at any time. In short, in order to take full advantage of the ubiquitous capabilities provided by the original fiber, it is possible to have a very narrow spectral width, and therefore the optical fiber is always flexible. It will be done. In other applications, information with zero additional force at various t points along the original fiber may be used. It is required to add one additional signal on the source fiber. For example, for military office type applications. Preferably! - Using fiber optics to transfer information from one office to another The ability to transmit information from one source to one or 31 other sites is required. Gold next day Ω! Leopard The applicant is Nori! Specifically, information is transmitted at a bit rate within an optical path of an optical fiber. ! In this technology, typically a laser or light I, which has a comparatively short duration but a relatively long anti-i1 darkness; A continuous pulse is generated. The original output of this optical book is FI, which is the original tg length, or is divided into more light lines. At least two of the optical paths have optical gates within them that have the ability to control the source pulses that are swept through them. Each gate is scanned separately according to individual information A. The output of the optical path is Typically, it is inserted into the optical path of Arashiichi, which consists of a Ri-mode optical fiber. The result is a bit rate equal to the sum of the two speeds of the different optical paths. Modified optical paths can be provided at various locations on this optical fiber, and this This makes it possible to add additional information onto the optical fiber. Reverse young crop smell In this case, the source fiber carrying the bit-rate information flow may be biased or have a forward gate ft in it. It is divided into multiple lines. A gate of one type can generate one piece of information in any time period. This method, activated in such a way that it is estimated that the signal is passing through, results in multiple destination paths, each with a portion of the information in the optical fiber. 21 Subaru 1 Deaf Calm Tomi 1 diagram is the first phase of Oichi after Koai is divided into 1 light sutra n of the number of rewards that are rewarded. IE21iN shows the amplitude graph for the A-type time cycle of the optical book; Typical variation sequences for different gates in the path and the resulting combination data Figure 5 shows the addition of additional data to the fiber at various points; This figure shows the counterintelligence technique according to the present invention that is recovered within the velocity data path. The following detailed description will explain how optical fibers operate at a relatively low rate of change compared to the resulting data flow! To transmit the original data stream at bit rate using Meno PL! Flashes to li. Both variable-tA and demodulation techniques are used for this; the term "optical length" as used here refers to the length of time the optical pulse is transmitted along the optical path. The term ``Gabi'' refers to a device that can change the intensity or other characteristics of an enhanced optical pulse in response to a change or return TAIN signal. A continuous stream of 71 pulses is provided.These pulses have a ratio of 71 as shown in Figure 2. Relatively long anti-j! It has a relatively short duration (1) compared to the interval (T). For convenience, any given pulse inverse i1 interval T is also referred to herein as a "frame". The original output of light 7 l10 is split and directed into multiple light paths (11 to 15). Inside these light guides, there are original gates (G1 to G5 that communicate with the transformer 16), which independently control the opening and closing of each gate. Since the optical path with polarization q has a different optical path length from the other destination paths, the delay of the pulse (PO) that is not changed by the optical path 1Q or A is t. The outputs of optical fibers til1 to X5 are then coupled onto the mouse optical fiber t7. Ru. Because of the different delays, the individual machines occupy different positions in time along this Keiichi source fiber. Kouko 10 is capable of producing a variety of conventional products including, for example, low-switch power lasers, dye lasers, etc. Any conventional optical system can be used, but preferably mode-locked semiconductor lasers are used. -zu is used. mode -zu will be located in Fabry Bello WA Sui. The time lSl interval between these pulses is It is determined by the length of HR. For example, it is formed on one side of a semiconductor laser and placed in a package with a 7-bit laser. First, the other side of the semiconductor laser is optically coated to allow the transmission of energy through it. Next, another yield force is created on the other side of the Fabry-peg gap so that the light pulse t4VLt can be reflected within R during this time. This is how Rezu's mo The output of the output port is no longer active, resulting in a spectrally pure output. chromatic dispersion as the light pulses are transmitted along the optical fiber. Next, the interval of the previous pulse is determined according to the length of the interval between the two pulses. Light travels about 1 foot per nanosecond in free space, so a 6-inch long 19-meter beam gives a round-trip distance of 12 inches, or about 1 pulse per nanosecond, resulting in a beam of 1 Gigabytes/sec.゜Gives the repetition rate. In addition to this, this lead book is It is possible to generate pulses that always have a short duration (1). For example, vA has a duration of 1 picosecond. As will be explained later, it is possible to obtain a pulse having a continuous period of RA in accordance with the present invention. According to the method described above, it is possible to transmit a modified pulse stream at a very high rate compared to the basic pulse repetition rate of light. To further explain the operation of the system shown in iE11:N, it should be noted that all of the optical cables G1 to G2 are in the % first "spot" and therefore the first part from the light source 10 is It is assumed that Lus can pass through light meridians 11 to 15. Figure 3 shows the light beam. The outputs of these five paths combined at the input of fiber 17 are shown. Pulse P1 is the pulse transmitted through the shortest transmuted meridian H(l +), and the next pulse SP2 is the pulse transported to the second enemy through the cylindrical cascade change path (12), and the same applies hereafter. The pulse transmitted through gate 2 (original route 12) is longer on light route 12 than on route 11, and is delayed by this amount, and even when other pulses are used, they arrive at the same stage little by little later. Do, other strange turtles or the one explained later! : Synchronized with the Ol unit. For the purpose of this, the pulse PO is transmitted through the sutra inscription 1B which is not filled with W. any sutra Until the subsequent pulse is transmitted through the path (e.g., Tall and Gate 1), the P4 cycle of the P4 cycle is at a time T, which is the same as the P4 cycle of the P4 pulse of the optical board 10. Therefore, it is given. The pulses extending yI from gate G1 to G5 have equal intervals as shown in diagram N3, and have pulses at intervals of T/6. However, this is not an absolute requirement; if these paths have four optical paths with different optical path lengths, the intervals between these pulses will not be equal. Furthermore, it is not necessary to use all of the time provided in each frame for the data channel; for example, some of this time may be used later. As will be clear, a single fiber can be stored in order to further expand the system by adding data from various sources along the optical fiber. The maximum number of R5 paths that can be combined on a bar is usually given by dividing the pulse repetition interval by the pulse +4 reading period E (T/t), which can be used in each frame. ``Time'' determines the maximum number of slots; however, in order to keep the error rate low enough, each slot is given +minutes of force and space, so that the maximum number of slots that can be used is Jl-number will be less than this number.Light' 10 previous output L; Since it is divided into many 18 meridians, the photo Q at the input of the 1/7 route is the rule of the light book. Therefore, if the gates G1 to G5 have a fixed amplitude gain, the resulting outputs from these paths will give a light beam of 1, and therefore ℃, where the inputs of the special names are. As shown in Figure 1, the light transformer 16 and the light transformer 16 can transform the transformer i into individual frames. This is synchronized so that it can be applied to the old gate at any given time in the system, which provides the optical output pulse from the optical system IG, which is converted into a signal by Yokoide Masu. This is done by providing 11 Go quasi-time points to the variable. Another method is to apply TFI or an optical signal to the variable seedling 16 or the optical board 10, thereby controlling when the optical board 10 generates a pulse. too Another possibility is to use a system that provides electrical or original synchronous pulses. There is also a way to control both the light source and the change-over device from the light source. In order to achieve this, the optical gates are preferably all placed at the same optical distance. This allows the device to apply the necessary variable A signals to all gates simultaneously to obtain the desired data sequence within any frame. However, the gate can be placed anywhere in the path including other lights by performing an appropriate A clause on the timing signal of this +5 signal, as shown in Figure 43 below. Next is Tomi 4! This section explains how information is transferred onto the pulses within the ritual path. In the vl view TG in the frame as an example, gates G1 and G4 are enabled, while gate? , 3 and 5 are turned off. Period tG+=, normally fundamental pulse anti-1! Is it shorter than the time reading interval (T)? and usually shorter than the duration of one light pulse T Alm (t). subordinate Therefore, the output of these five pulses is coupled onto this optical fiber by providing the pulse 11 shown in FIG. It can be obtained as follows. The change is then repeated in the next frame period. and change to the t state to serve the so-called pulses again. Ru. Normally, the odd gain is to use the 1-ta gate independently according to the information A of the chant. However, two or more gates may be connected at the same time! ! Redundancy can also be added to the transmission to reduce errors or for other purposes. It is also possible to provide two (or more) frames waiting for the same information for redundancy purposes by making the period tG larger than T. It is clear that this method of communication has many advantages. To 1, this method According to this method, it is impossible to be rude or pure in terms of slavish vectors. It is better to use a stylish type of light register. This is because, in this method, the optical plate is not destroyed and thus mode-locking or other stabilization methods can be used to obtain a spectrally pure optical plate. . Second, some types of light obscurity are difficult to change at high temperatures, even though they produce very fine pulses. However, according to this method, It is possible to use the Una Hikari Book. In straw 3, the depleted transformation Gut is relatively L: It operates at a slow barbaric level. This allows the gate device to be manufactured and operated more easily than in cases where the gate device is required to operate at high grass levels. Finally, the t-part of the variable +:Il device can also operate at a relatively low speed. Furthermore, the advantages of this method are that the pulse spacing can be changed freely, and if it becomes necessary to increase the capacity, the number of channels that can be used mainly in the layer can be increased. ．． Furthermore, according to this method, O It is possible to add information Ii1 at will. In the straw 5 map, the first fi The flow of information pulses Pl. ．． ．． Carry P5. Here, in the frame as an example of Figure 4, slots P1 and and P4 are 1" on, producing pulses P1 and P2, while slots P2, P3, and P5 are 1" off. Is the optical fiber 52 a light source (not shown)? It carries a continuous flow of pulses (PO) that do not change. At the desired position, a portion of the original energy is directed from the fiber 52 to the path 53 through the tip splitter (54). I get kicked. A light gate G6 is placed within the Keiken 53, and this exemplary frame is transformed by transformer 56 to produce a pulse modulation pulse (P6) that is indicated as "on" during the corresponding slot in the system. The optical path length of path 53 is Pl. ．． , the choice is made to delay the battle against Yubarusu from P5. Next, the incident of incident 53 The fiber is spliced onto fiber 51 and P6 is added to the information stream on fiber 51 at point 55. Weird: l! The pulse generator 56 is synchronized with a continuous pulse stream P O on the fiber 52 . This synchronization is the first energy source of the Vanores PO that increases fiber 52. By adding Denki No. 11 to Reggie's partial pinch, or by adding Denki No. can be distanced by other methods. If necessary, additional extension paths can be split at point 54, independently transformed, and combined at point 55 to obtain additional independent information channels. You can also do it. In a similar manner, it is also possible to obtain additional access points at arbitrary points along the length of the fiber. These devices can be added until all timeslots in the frame are used. Since the method according to the present invention has such capabilities, the present invention is particularly effective in the environment of the office quib. It has a wide range of applications in the original fiber network (LANS). In such applications, the ability to send and receive information at various points along the length of the fiber is less important than very high data rates. In some cases, a light emitting diode is used as a non-transformable light source. The fiber is of the multimode type. Furthermore, the use In this case, there is no need to change the light flow in the vicinity of the light leak 10, as shown in m19, and all modulated destination paths are located at various distances from the light source, as shown in n52. ,The above technique f+ can also be applied to the corresponding recovery technique.As shown in Figure 6, what is the optical power of 17 optical fibers? ! The number of optical paths, 61, is divided into 65. The demodulator gates D1 to D5 are controlled by the demodulator 66, while the demodulator 66 clocks the opening and closing of the demodulator gates. As shown in Figure 6, if the length of the path is significant, the return gate can be flashed at the same time. However, this period is short enough so that only 1 pulse per frame passes through it. Unbiased i! [The output of the path is the output of the change path in the corresponding change path. Corresponds to vals. If all of the gates are opened at the same time by Reverse IIIi, since Valse P1 first appears at the Reverse gate input, this means that the stable is also restored in a long path (65), and then the Valse P5 is demodulated through the shortest path (6l) circle Ru. The output of the tl pumping path is typically applied to a transducer (67-71) to convert the prepulse into an electrical pulse. The advantages mentioned above also apply to this case. In other words, this The device can operate at pulse speeds that are only a fraction of the speed of unaltered light. Furthermore, i! ! : To transmit the optical output of L5 gate to other destinations. It is also possible to connect to a bar. It is also clear from the ratio of χ5[F] to the variable 2 technique that the path can be placed at any point along the length of the fiber. Revival: 2I straw 66 game hDI. ．． ．． To synchronize the opening of D5, a synchronization pulse is sent from the odd J-rule. This can be accomplished by using the unaltered route (l8) from Guangkan, as shown in Figure 1. This synchronization pulse is shown in Figure 33. As shown, the amplitude of the changeable true pulse has a specific amplitude. As a 5i4 method, l! For the purpose of the first phase, pulse characteristics such as amplitude and pulse characteristics, such as light polarity, pulse length, and pulse wavelength, may be used. There are far different synchronization techniques, such as 2K5 (which uses a separate optical fiber to carry the synchronization pulses, as shown in IL). Other methods are also possible. The light i that exists clearly in the simultaneous occurrence of the synchronized pulse and the information light pulse! It is also possible to use the seven techniques if+. For example, the combination of two optical inputs at the same time can use a nonlinear optical medium that produces an output of twice the number of cycles a. One of these optical inputs is a synchronous pulse carried by a 1-wire optical fiber (eg, PO on a 5-[F] fiber 52). The other input is the information flow (g+!, for example, P1 to P6 on 159 fibers 51). To obtain the desired optical coincidence, the synchronization pulse is split into a true length optical path and gated D I . , , is added to the match extractor instead of D5. Synchronous optical pulse (PO) also It is added to the unbalanced match extractor. The matching extractor for ffl is as described above. Similarly, outputs are generated on each return path for each pulse on the corresponding modulation path. Alternatively, EIX+! is split at the coincident side output device input! It is also possible to use a method that gives a relative delay to the = of the pulses, while not giving a relative delay between the information pulses. Optical coincidence extraction techniques require the use of electrical repeaters that require the electrical converter gate to be opened for a short enough period of time to separate the preceding pulses as required in Figure 6. It disappears. We conducted an experiment on such a coincidence technique using the nonlinear optical properties of iodine and lithium. ``3. Lithium boronate and other nonlinear optical crystals double the !@ depth number of light incident on the crystal near the phase matching angle (that is, convert dark light into solid light). This device generates light with an MR number of 2f! only when two beams enter the crystal at the same time, and with only one of these two beams, 2P & man light is generated. One of the beams carries the information pulse and the other beam carries the synchronization pulse.The polarized beam has a phase matching angle and some angle (for example, 5 degrees). The two beams are focused on the lever crystal. It was decided to correct the ship & ship directed at the same sport on the crystal: 21W5 Therefore, the desired information flow can be output as a pulse that enters from the crystal at the same channel modulation temperature. In one experiment, the mode lock clock Lipton Pump Dye Rebu has approximately 3 milliwatts at the wafer length of a 0.83 mike meter. The semiconductor gate generates a synchronous pulse of 1 milliwatt on the crystal. A signal pulse was generated. This pulse was found to have a duration of about 1 picosecond and an interval of 310 nanoseconds. If the path length for the information flow or synchronous pulse flow is changed to about 10 picoseconds, the output with twice the number of cycles will disappear, or it will be 1 ratio. It was. 11 to 15 and 61 to 65 are different from that. L's change bar G1 to G5 and j! Even if it is a free hundred = path with D5 from Tsunaehiki. deer However, it is particularly advantageous to use fiber optics for these paths. It is also possible to form a gate on the tombstone's light character toad and obtain a light device using 21. In this case, for example, a specific optical path length can be obtained by changing Iff and applying a loop fold to this path. Depending on the material, the refractive index may change when an electric field is applied to the material. In addition, there are materials that change their length when exposed to energy, and this allows the length of a path with a certain length to be changed. On the other hand, it is also possible to hold the position of manager of this business line for a long time. Wear. Additionally, the converter 16 and demodulator 66 may be formed on separate integrated chips, or may be additionally coupled on an electron-optical chip bridged from the original path and gate. I'll come. i! Tsugate (D!.,,D5) and Hakudeki (67...71) are expressed as different tricks as shown in Kawara 6, or these! It is also possible to combine 1 energy into a single device, for example, the first energy can be combined with 1 energy! Ki energy The generator responds to an information pulse only when there is a synchronization pulse or an information pulse that converts the It can also be controlled electrically or optically so that the Nonlinear photons can also be used to reduce the duration of the light pulse before or after the deformation. example For example, using an optical fiber whose refractive index depends nonlinearly on the electric field, Techniques for generating so-called "soliton" pulses are well known in the art. child For further inspiration, see U.S. Pat. No. 4,406,516, co-assigned with the present invention. For the λ pressure 4, a well-designed optical fiber or other nonlinear device can be used before or after the gate (Gl-G5) in the optical fiber (I+-15). In this case, the term used here, pulse duration Interval (1) occurs during the duration after pressure i. You can use ζ:GaAIAs for the base of each gate. This device uses electronic pulses to When it is biased, it is concentrated in the active region, and the current pulse coincides with the current pulse by one width.The first width is conventionally DC electric? View under injection! It was done. :! Nobuaki's joint research idea discovered that pulse amplification with a length of a few picoseconds could be achieved by using GaAIAs progression and Quip's strength gain. When the current pulse is injected with this tie to the original pulse, when the current pulse is active, a coefficient of 10 will occur, and 10,000, and when the current pulse is active, a coefficient of 10 will occur. occurs with a factor of 10, resulting in It turns out that you can get at least a 100 degree difference. Stranger than IGHZ. 2i far, l or night. In this way, the information in the form of the electronic pulses present in the TLL, together with the gain, can be transferred to a single pulse of arbitrary length. An example of a winning gate and its operation is shown below. It's fortune telling. A striped Gao4 A I6.1 μ. which bombards protons without inducing light into the activity center of the light. S was used. For more information, see the Journal of Luminescence. o! , 7, page 310, 19732. A. A sentence by D Apko (L.A.0'^Sro ko): ``EJ ■ Eyo. . . . , εmittξr theft and Detector@) with 6 decoys. In order to prevent self-oscillation of the guide by reducing the reflector on the guide surface by about 1%. In the layer of Si 02 Anti-reflective coating was applied. This die was connected to the Iw4 stud, and a 2 nanosecond voltage pulse from a pulse generator was injected into it. The light source includes a dye rape synchronously pumped by a mode 02 krypton laser. - was used. The dye used was 7xazine 750, which has a 10 ps pulse at 81 MHz frequency and a tuning range of 7aoo I know it will be a long time. pa The pulse generator was synchronized to a mode-locked RFI operating at half the pre-pulse rate. The output of the dye laser is focused on one face of the active region of the die and is ejected by a beam emerging from the opposite face with a rise time of less than 1 nanosecond. This signal was displayed on an optical scope and photographed. Daio The output wavelength of the code was 8300B. A 40.5 MHz electronic pulse tray with an amplitude of 2.5 was injected into this diode, and each pulse in this tray had a duration of 2 nanoseconds. The relative delay is the current pulse of ffl When the light pulse was multiplied by 3x so that the light pulse was 1 in time, the intensity increased by a factor of about 100 from one pulse to the next. The ratio of the output intensity and input intensity of these pulses A net gain with a factor of 8-10 was determined from the comparison. This is 1 including all coupling losses to the die. The source pulse passing through the guide in the absence of the current pulse showed a loss of weight by a factor of 10 due to the bunt gap gap sucking. In other words, under these conditions, a difference of about 100 was obtained. At X input strength, gain saturation It was discovered that it was a peaceful battle. At an average input power of 5mW, the gain was reduced to about 1, resulting in only 1o modulation. At input powers below approximately 0.1 mw, the gain was linear. In Fusouwa state, at least IGHZ's Hentsu iX! It was confirmed that this is possible. These gates are not necessarily required to provide 1 amplitude gain. Relatively flat tubes, such as Ti(to), overcome the losses incurred in splitting sustained pulse flows using gas lasers. I can do that. In addition, the gate has three different meanings (not included in the tzli issue): Light or sound! You can also use the i number to control it. Although the gates Gl-G5 and D1-O5 were described as controlling the Wl width of their corresponding pulses, the gates Gl-G5 and D1-O5 have been described as controlling the Wl width of their corresponding pulses, but the gates Gl-G5 and D1-O5 have been described as controlling the Wl width of their corresponding pulses; It may also be used to control other properties of the optical pulse for other purposes. For example, the two lengths of a pulse of light can be varied in response to a variable signal using a suitable heterodyne device. Alternatively, a switch can be used to divert the pulses out of the optical path. Yet another method It is also possible to modulate the radial nature of the optical pulses by using the following method, in which case a mute protected fiber (17) is used for transmission. Carry out these *reprimands against the light pulses Excessive equipment for the purpose of The device for dividing the pulses into a plurality of light ffl (19 in I11ii!) and for combining the forces of the sutra mei (20 in Figure 1) can be realized by elements well known in the art.

It is also possible to use other elements. While the present invention provides significant benefits to fiber optic transmission systems, it is contemplated that other forward path media may be used.
