Description

  The present invention relates to an optical parallel computing element for performing higher-performance parallel computation at higher speed by incorporating optical information of each other during optical parallel computation.

  With the recent demand for higher speed and higher performance of information processing apparatuses, parallel processing is required. For this reason, a parallel arithmetic element in which a plurality of digital arithmetic processing circuits are incorporated is provided. However, for analog information, parallel digital arithmetic must be performed after each signal is converted into a digital signal. For this reason, an arithmetic element capable of calculating a plurality of analog signals in parallel at the same time in analog form is required for speeding up the arithmetic processing.

  A conventional analog arithmetic element uses a conventional semiconductor element such as an operational amplifier for a single circuit. In a plurality of circuits, an analog signal is first converted into a digital signal, and then a plurality of digital signals are processed. Was. Therefore, in order to perform analog operations of a plurality of analog signals in parallel, the same number of analog-digital conversion circuits as the number of input circuits are required. In addition, as the number of circuits increases, there arises a problem that it becomes difficult to synchronize a plurality of analog-digital conversion circuits.

  On the other hand, an element that performs calculation using light has been proposed. FIG. 13 is a cross-sectional view schematically showing the configuration of a conventional optical arithmetic element. This optical computing element includes a plurality of two-dimensionally arranged optical cells 51, and each optical cell 51 contains a light-responsive substance 54 that responds when receiving light information in a partition composed of a partition 52 and a bottom 53. doing. Each optical cell 51 is irradiated with light 56 having a predetermined wavelength by the arithmetic light irradiation device 55, and the photoresponsive substance 54 in the optical cell 51 irradiated with the light 56 exhibits photoresponsiveness and detects its state. Thus, the calculation is performed.

  However, such conventional optical arithmetic elements are performed by independent optical cells 51 when performing parallel processing, and information is exchanged between adjacent optical cells 51 during parallel arithmetic. Not done. If computation between adjacent optical cells 51 is necessary, parallel computation is temporarily stopped, computation between optical cells 51 is performed, and then parallel computation is resumed.

Accordingly, there has been a problem that as the amount of information exchanged between the optical cells 51 increases, the calculation speed of the parallel calculation by the plurality of optical cells 51 decreases. In parallel computation, since processing such as data rearrangement is necessary for pre-processing for performing parallel computation, there is a problem that computation by a single optical cell 51 is faster in some cases.

  Hereinafter, the present invention will be described in detail.

  FIG. 1 is a plan view schematically showing a configuration of an optical parallel arithmetic element according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view showing an optical cell configuration of the optical parallel arithmetic element according to the first embodiment. FIG. 3 is a diagram illustrating the principle of the optical parallel arithmetic element according to the first embodiment.

  The optical cell 11 has a space partitioned by a partition wall 12 and a bottom portion 13, and a photoresponsive substance 14 that responds when receiving light information is accommodated in the space. The partition wall 12 is made of a light-transmitting transparent material and is provided with silver columns provided at intervals corresponding to the wavelength of light having a specified wavelength Wf to be transmitted, or silver is coated on a portion in contact with the light transmission side (The structure 15 coated with silver is shown in FIG. 1). Here, the interval corresponding to the wavelength of the light having the specified wavelength Wf indicates a gap (Wf−0.1 × Wf) that is shorter in the range of about 10% than the specified wavelength Wf. Although the upper side of the optical cell 11 is described as opening, it is assumed that the photoresponsive substance 14 is sealed in the apparatus. This sealing may be performed by a method of covering with a light transmissive material, or may be encapsulated. The photoresponsive substance 14 in the optical cell 11 can be irradiated with light from above. Here, the upper side refers to the upward direction in FIG. 2 and may be in an arbitrary direction in actual use. In the present embodiment, a mirror is not provided on the bottom 13 as in the second embodiment to be described later, but whether to provide a mirror depends on the type of molecule used as the photoresponsive substance 14 and the calculation method, Alternatively, it can be determined by the size of the optical signal to be obtained.

  As the material of the optical cell 11, a light transmissive transparent material such as quartz, glass, silicon nitride, silicon oxide, sapphire, transparent alumina, or the like is used. As the dimensions of the optical cell 11, for example, those having a length of about 100 μm, a width of 100 μm, and a depth of about 200 μm are used, but are not limited thereto. The partition wall 12 is provided with silver support columns provided at intervals corresponding to the wavelength of the light having the specified wavelength Wf to be transmitted as described above, or on the light transmission side. Silver is coated on the part that touches. Here, the silver support is provided by selectively silver-plating a portion including the silver support. The light-responsive substance 14 emits light distributed over a predetermined wavelength region when irradiated with light Wi having a predetermined wavelength, and the emitted light passes through the partition wall 12 and is adjacent to the optical cell 11 as light having a predetermined wavelength Wf. In the state where the light having the predetermined wavelength Wi is irradiated on the adjacent optical cell 11, a material that generates bright light (high emission intensity) when the light having the specified wavelength Wf is incident is used. . Examples of the photoresponsive substance 14 include Benzoic Acid, 2- [6- (ethylamino) -3- (ethylimino) -2,7-dimethyl-3H-xanthen-9-yl] -ethyl ester, mono-hydro- laser dyes such as chloride (hereinafter abbreviated as Rhodamine 6G), o- (6-Amino-3-imino-3H-xanthen-9-yl) -benzoic acid (commonly known as Rhodamine 110)), methanol, ethanol, And those dissolved in a solvent such as dimethyl sulfoxide.

  Here, the structure 15 coated with silver and the silver support will be described. FIG. 7 is a plan view for explaining the structure 15 coated with silver, and FIG. 8 is a perspective view schematically showing the structure 15. As shown in FIG. 7, the structure 15 has a constant thickness s3, and a plurality of them are spaced apart at a pitch s2 in the arrangement direction to form a slit having a width s1, which is a waveguide for transmitted light. As a role. The interval s1 between the slits, that is, the portion that transmits light is set to be shorter than the wavelength Wf of the transmitted light. Incidentally, as an example of dimensions, when the wavelength of transmitted light is 623 nm, s1 = 150 nm, s2≈600 nm, and s3 = 300 to 500 nm.

  An example of the silver coating method is shown in FIG. For example, as shown in FIG. 9 (a), the portion coated with silver and the quartz in which the optical cell is processed are covered with a resist except for the portion coated with silver as shown in FIG. 9 (b). As shown in FIG. 9, silver is deposited by a sputtering process, and silver other than the portion coated with silver is removed by lift-off as shown in FIG.

  FIG. 10 shows an example of a process for producing a silver support. For example, as shown in FIG. 10A, gold is plated on the base silicon and the quartz on the wall surface, and these materials are bonded together as shown in FIG. Next, as shown in FIG. 10 (c), the optical cell portion is covered with a resist, and anisotropic etching by DeepRIE is performed as shown in FIG. 10 (d). Next, as shown in FIG. 10 (e). The portions other than the place where the silver support is made are covered with a resist, and the silver support is made by a silver plating process as shown in FIG.

  The structure 15 coated with silver or the silver column transmits light of the specified wavelength Wf as follows. Normally, light cannot pass through a hole narrower than the wavelength due to the diffraction limit. However, in the case where holes are formed at intervals of the same period as the wavelength to be transmitted and the material of the irradiated portion is silver, the distribution of electromagnetic waves is generated on the surface as shown in FIG. The electromagnetic wave propagates like a tube, and thereafter, the electromagnetic wave is generated on the surface opposite to the irradiation surface, and light having a specific wavelength is generated. By this series of mechanisms, light having the same wavelength as the interval between the holes is transmitted (Non-Patent Document 1). Since this effect has an effect on the polarized light which is also applied to the slit, the selected light is emitted from the light emitting surface (lower side in FIG. 11).

  The calculation operation will be described. First, as shown in FIG. 3I, a one-dimensional array of optical cells is considered. The light-responsive substance 14 placed in the optical cell A (11) is irradiated with light having a wavelength Wi. At the same time, the light-responsive substance 14 placed in the optical cell B (11) is irradiated with light having the wavelength Wi. At this time, light having a wide wavelength distribution is emitted from the photoresponsive substance 14. A part of the light emitted from the optical cell A (11) is directed to the left adjacent optical cell and the right adjacent optical cell B (11), and a part of the light emitted from the optical cell B (11) is adjacent to the left. The optical cell A (11) and the optical cell C (11) on the right are directed to the optical cell A (11) by the partition wall 12 provided with the structure 15 coated with silver. And is transmitted to the optical cell B (11) and irradiated to the photoresponsive substance 14 placed in the optical cell A (11) and the optical cell B (11), respectively. At this time, the light irradiated to the photoresponsive substance 12 in the optical cell A (11) and the optical cell B (11) becomes a light amount of a predetermined amount or more, and the photoresponsive substance 14 is excited and emits light strongly (FIG. 3 (ii), (iii)). In addition, light irradiation to only the optical cell adjacent to the left of the optical cell A (11) or only the optical cell C (11) is insufficient in light quantity, and light emission like the optical cell A (11) or the optical cell B (11). Does not happen. The presence / absence of light emission and its intensity are the calculation results of the adjacent optical cells 11. Therefore, by using the change of the photoresponsive substance 14 that occurs when light information is simultaneously input from a plurality of optical cells adjacent to the specific optical cell, it is possible to perform calculation using a plurality of input information.

  As described above, the principle of the optical parallel computing element of the present invention has been described by taking the case of using a one-dimensional array of optical cells as an example. Of course, in the present invention, an element configuration in which a number of optical cells are two-dimensionally arrayed is used. Can do.

  Next, a second embodiment of the present invention will be described. 4 is a plan view schematically showing the configuration of the optical parallel arithmetic element according to the second embodiment. FIG. 5 is a cross-sectional view showing the configuration of the optical cell of the optical parallel arithmetic element according to the second embodiment. These are the principle explanatory views of the optical parallel arithmetic element according to the second embodiment. 4 to 6, the same elements as those in FIGS. 1 to 3 are denoted by the same reference numerals.

  Similar to the first embodiment described above, the optical cell 11 has a space partitioned by the partition wall 12 and the bottom 13, and a photoresponsive substance 14 that responds when receiving light information in the space. Contained. The partition wall 12 is made of a light-transmitting transparent material and is provided with silver columns provided at intervals corresponding to the wavelength of light having a specified wavelength Wf to be transmitted, or silver is coated on a portion in contact with the light transmission side (The structure 15 coated with silver is shown in FIG. 4). Further, the bottom portion 13A has a triangular cross section as shown in FIG. 5, and a mirror 16 is formed at a portion corresponding to the two sides as shown in the figure. This mirror 16 is provided in order to improve the exchange of light information with the adjacent optical cell 11. The second embodiment is different from the first embodiment in the shape of the bottom portion 13A and the configuration in which the mirror 16 is provided, and the other configurations are the same.

  The calculation operation will be described. First, consider a one-dimensional array of optical cells as shown in FIG. The light-responsive substance 14 placed in the optical cell A (11) is irradiated with light having a wavelength Wi. At the same time, the light-responsive substance 14 placed in the optical cell C (11) is irradiated with light having the wavelength Wi. At this time, light having a wide wavelength distribution is emitted from the photoresponsive substance 14. A part of the light emitted from the optical cell A (11) is reflected by the mirror 16, and goes to the optical cell B (11) on the left and the right adjacent optical cell (not shown), and the light emitted from the optical cell C (11). Is reflected by the mirror 16 and goes to the optical cell B (11) on the left and the optical cell D (11) on the right, but has a specified wavelength by the partition wall 12 provided with the structure 15 coated with silver. Light of only Wf is transmitted and irradiated to the photoresponsive substance 14 placed in the optical cell B (11). At this time, the light irradiated to the photoresponsive substance 12 in the optical cell B (11) becomes a light amount of a predetermined amount or more, and the photoresponsive substance 14 is excited and emits light strongly (FIGS. 6 (ii) and (iii). )). Further, light irradiation to only the optical cell A (11) or only the optical cell C (11) is not enough to emit light. The strong light generated as a result of the above phenomenon is the calculation result of the adjacent optical cell B (11) and the optical cells A (11) and C (11). Therefore, by using the change in the photoresponsive substance 14 that occurs when light information is simultaneously input from a plurality of optical cells adjacent to the specific optical cell, calculation using a plurality of input information becomes possible.

  As described above, the principle of the optical parallel computing element of the present invention has been described by taking the case of using a one-dimensional array of optical cells as an example. Of course, in the present invention, an element configuration in which a number of optical cells are two-dimensionally arrayed is used. Can do.

  Further, in the first embodiment, attention is paid to the adjacent optical cells, and in the second embodiment, attention is paid to the specific optical cell and the adjacent optical cells. It can be performed.

  In the second embodiment, the case where each optical cell has a square shape in plan view and the bottom portion has a quadrangular pyramid shape has been described as an example. However, each optical cell has a planar shape. As the shape of the regular triangle, the shape of the bottom is a triangular pyramid, these may be finely arranged, the shape is a regular hexagonal shape in plan view, the shape of the bottom is a hexagonal pyramid, These may be arranged in a honeycomb shape. These can be produced by simply changing the pattern of the lithography mask when micromachine technology is used to form each optical cell. Further, the shape of the bottom of each optical cell may be flat at the top.

  Next, the present invention will be described in more detail with reference to examples.

  FIG. 12 is a diagram illustrating the principle of the optical parallel arithmetic element according to the embodiment of the present invention. The optical parallel computing element of FIG. 12 has four optical cells, but this is for illustrative purposes, and in practice, a required number of optical cells can be two-dimensionally arranged.

  In the optical cell, quartz was finely processed by a micromachine technique to form a space partitioned by a partition wall and a bottom as shown in FIG. Further, silver pillars were provided on the partition walls at intervals of 623 nm by the method shown in FIG. 10 so that only light of 623 nm was enhanced. Gold was deposited on the bottom of the triangular cross section to provide a mirror. This mirror was formed so that light entering from above was reflected through the partition wall toward the adjacent optical cell. In the optical cell, a mixed solution in which 0.75 g of Rhodamine 101 was dissolved in 1000 ml of a solvent (methanol) was placed as a photoresponsive substance.

  The operation of this optical parallel computing element will be described. As shown in FIG. 12 (i), the photoresponsive substance Rhodamine 101 placed in the optical cell A is irradiated with light having a wavelength Wi = 308 nm and simultaneously placed in the optical cell C. The same photoresponsive substance was irradiated with light having a wavelength of 308 nm. At this time, Rhodamine 101 in optical cells A and C was excited by light having a wavelength of 308 nm and emitted light. This light was reflected by the mirror, and only the light having a wavelength of 623 nm was enhanced by the partition wall and irradiated to the optical cell B. The Rhodamine 101 of the optical cell B simultaneously received the enhanced light of wavelength 623 nm from the optical cells A and C, and strongly emitted light of wavelength 623 nm by stimulated emission. When only the optical cells A and C were irradiated with light, the optical cell B did not have enough light to cause the Rhodamine 101 to emit light, and unlike the optical cell D, strong emission at a wavelength of 623 nm did not occur. As a result of this series of phenomena, strong light generated in the optical cell B becomes an adjacent calculation result.

  In addition, for light having a wavelength Wi of 488 nm, a mixed solution in which 2.5 g of Rhodamine 101 was dissolved in 1000 ml of solvent (methanol) and a mixed solution in which 0.5 g of Rhodamine 101 was dissolved in 1000 ml of solvent (methanol) were also used. When the same calculation as described above was performed, similar results were obtained.
