Specific embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
Realize a kind of implementation such as Fig. 1 of all-optical logic XOR gate.
From travelling-wave semiconductor amplifier (soa), make the parameter of four soa essentially identical, and so that its injection current is kept
At higher value (near 0.5a), to reduce the impact to output for the carrier recovery time.Because this programme uses unsaturation
Soa working area under state, internal reflected light has considerable influence to output, and therefore, the front and back end reflectance of soa is as far as possible little, with
Reflectance is optimal for 0, is allowed to the state as far as possible amplified close to traveling wave, with reducing reflected light, the output of soa is affected.

Interferometer, remaining each element is distributed in interferometer two-arm and carries out light splitting, amplification, filtering, combining etc. to three road optical signals of input
Operation.
Centre wavelength is λ1Pulsed light a light carry signal to be processed, after first power splitter 1 of 50:50, point
Become the equal light of two beam powers, interferometer underarm connects the first PCU Power Conditioning Unit 13, adjust the light work(making on underarm on interferometer
Rate is different.Centre wavelength is λ3Clock light after 50:50 the 3rd power splitter 14, make clock light in interferometer upper arm and interferometer
Underarm gets identical initial phase and the light of equal-wattage size.On the interferometer that the light of its interferometer upper arm is obtained with a signal
The light of arm couples through the first bonder 2, enters the first cascade semiconductor optical amplifier soa3, its interferometer through certain short distance
The light of the interferometer underarm that the light of underarm is obtained with a signal couples through the 4th bonder 15, enters fourth stage connection through same distance
Semiconductor optical amplifier soa16.Wherein, the light exporting upper and lower ends mouth after clock light goes out the 3rd power splitter 14 arrives through same distance
Reach the first bonder 2 and the 4th bonder 15.Put in the first cascade semiconductor optical amplifier soa3 and fourth stage connection semiconductor light
After big device soa16, reach the first filter 4 and the 4th filter 17 through same distance respectively it is ensured that filtered device
A light is filtered substantially completely afterwards makes more clock light pass through simultaneously as far as possible.After going out filter, on interferometer, underarm is through phase
Same distance reaches the second PCU Power Conditioning Unit 5 and the 3rd PCU Power Conditioning Unit 18, after through same distance to the second bonder 8 He
3rd bonder 19.This ensures that there in the impulse action of no signal a, interferometer upper and lower arm clock light phase is identical.
Centre wavelength is λ2Pulsed light b light carry signal, after second power splitter 6 of 50:50, interferometer upper arm
Connect the second PCU Power Conditioning Unit 7, adjust the beam splitting capabilities difference making the upper and lower arm of interferometer.The light of the upper and lower arm of interferometer respectively with
Co-implanted second bonder 8 of light through the second PCU Power Conditioning Unit 5 and the 3rd PCU Power Conditioning Unit 18 and the 3rd bonder 19.
Afterwards, the light of the upper and lower arm of interferometer arrives separately at the second cascade semiconductor optical amplifier soa9 and third level connection through same distance
Semiconductor optical amplifier soa20, then arrives separately at the second filter 10 and the 3rd filter 21 through same distance.Filtering
Device wavelengths centered be aligned clock light basic frequency, and take 5nm about bandwidth it is ensured that after filtered device b light substantially complete
Entirely filter and so that more clock light is passed through simultaneously as far as possible.Adjust interferometer, upper underarm light path afterwards, make interferometer upper arm and interference
When instrument underarm enters combiner 12 jointly, the equivalent optical path that experienced.Interferometer upper arm has phase shifter 11 value will ensure
180 °, so that when no signal inputs, light energy output produces cancellation, thus being consistent with XOR.
The principle that Fig. 1 device realizes XOR function is as follows:
Two bundle injection lights are when being logical zero, clock light after waiting than light splitting, in upper and lower two-way through identical soa twice
Amplify it, in interferometer upper arm, size is 180 ° of the clock optical signal phase generation making interferometer upper arm of 180 ° of phase shifter
Delay so that up and down light have 180 ° of phase contrasts, after being connected to power combiner afterwards, occur destructive interference so that output letter
Number be " 0 "；
When two bundle injection lights are logical one, the upper and lower splitting ratio of light pulse of a light is different, in the upper and lower arm of interferometer
The carrier of soa receives different degrees of consumption, produces different refractivity, so that clock light is upper and lower through interferometer
Certain phase contrast is produced, because the light splitting ratio of the light splitting ratio of b and a is contrary, so b is to interferometer upper arm the after arm soa
Two cascaded semiconductor image intensifer soa9 modulating actions are equal to a and join semiconductor optical amplifier to the interferometer underarm fourth stage
The effect of soa16, and to the interferometer underarm third level join semiconductor optical amplifier soa20 be functionally equivalent to a on interferometer
Arm first cascades the effect of semiconductor optical amplifier soa3.So that after two-stage soa, clock optical interferometer upper and lower arm phase place
Difference is 0.After the phase shifter, interferometer upper arm is 180 ° compared with the phase contrast of interferometer underarm, and destructive interference occurs, so that
Output signal pout is " 0 "；
When in two bundle injection lights, only one of which is " 1 ", that one-level for " 1 " carries out phase-modulation to clock light, due to
Xpm effect, upper and lower two-way produces certain phase contrast, still has non-zero phase contrast in output, so that avoiding after phase-shifter
Generation destructive interference is so that output signal is " 1 ".In view of the amplification of soa itself, because flashlight is put in the first order
It is easy to after big self phase modulation occur so that output is unstable in the second level, this programme is connected to work(between two-stage
Rate adjusting means, the PCU Power Conditioning Unit of the upper and lower arm of interferometer takes identical attenuation quotient, thus ensureing the interferometer of system
Upper and lower arm balance, so that output is stablized and ensure " 1 " pulse power roughly the same.
Realize another kind of implementation such as Fig. 2 of full light XOR gate.
From general semiconductor amplifier, make the parameter of four soa essentially identical, and it is larger so that its injection current is maintained at
Value (near 0.5a), to reduce the impact to output for the carrier recovery time.Because this programme uses under unsaturated state
Soa working area, internal reflected light has considerable influence to output, and therefore, the front and back end reflectance of soa is as far as possible little, with reflectance
It is optimal for 0, is allowed to the state as far as possible amplified close to traveling wave, with reducing reflected light, the output of soa is affected.
Centre wavelength is λ1Pulsed light a light carry signal to be processed, the first power splitter through 50:50) after, point
Become the equal light of two beam powers, interferometer underarm is followed by the 4th PCU Power Conditioning Unit 33, adjust the light work(making the upper and lower arm of interferometer
Rate is different.Centre wavelength is λ3Clock light through the 2nd 3db bonder 23 upper end injection after, make coupling export clock light interfere
Instrument upper arm and interferometer underarm get equal-wattage but phase contrast is 90 ° of light.It is dry that the light of its interferometer upper arm and a signal obtain
Interferometer upper arm light couples through the first bonder (2), enters the first cascade semiconductor optical amplifier soa3 through certain short distance, its
The interferometer underarm light that the light of interferometer underarm is obtained with a signal couples through the 4th bonder (35), the distance through same length
Enter fourth stage connection semiconductor optical amplifier soa36.After soa (24) and soa (36), reach filtering through same distance respectively
Device (25) and filter (37) it is ensured that after filtered device a light substantially filtered completely and made more clocks simultaneously as far as possible
Light passes through.PCU Power Conditioning Unit (26) and the power adjustments dress of the upper and lower arm of interferometer after going out filter, is reached through same distance
Put (38), after through same distance to bonder (29) and bonder (39).This ensures that there in the impulse action of no signal a
When, interferometer upper and lower arm clock light phase difference keeps 90 °.
Centre wavelength is λ2Pulsed light b light carry signal, after second power splitter 6 of 50:50, interferometer upper arm
Connect the 3rd PCU Power Conditioning Unit 7, interferometer glazing, underarm light respectively with flow through the second PCU Power Conditioning Unit 5 and the 4th power and adjust
The light of regulating device 18 co-implanted second bonder 8 and the 3rd bonder 19 respectively, after arrive separately at second through same distance
Cascaded semiconductor image intensifer soa9 and second cascade semiconductor optical amplifier soa20, then arrives separately at the through same distance
Two filters 10 and the 3rd filter 21, filter wavelengths centered be aligned clock light dominant wavelength, and take 5nm about
Bandwidth it is ensured that after connecing filter b light substantially filtered completely and so that more clock light is passed through simultaneously as far as possible.Adjust afterwards and interfere
Instrument upper and lower arm light path, when making interferometer upper arm and interferometer underarm common entrance the first 3db bonder (22), the light being experienced
Journey is equal.Because 3db bonder is by the optical coupling process of upper and lower for interferometer arm, can add in the generation of interferometer upper arm
90 ° of phase contrasts, so that in the case that input is for " 0 ", luminous energy produces cancellation, thus being consistent with XOR.
The principle that Fig. 2 realizes XOR function is as follows:
Two bundle injection lights are when being logical zero, clock light after waiting than light splitting, in upper and lower two-way through identical soa twice
After amplification, clock optical signal couples output in outfan, because light splitting and coupling are all 3db bonder, therefore interferes in output
When instrument upper arm accepts result, the light that output result is the upper and lower arm of interferometer is interfered to produce cancellation output result after 180 ° of phase shifts.
Output signal is made to be " 0 "；
When two bundle injection lights are logical one, the upper and lower splitting ratio of light pulse of a light is different, in the upper and lower arm of interferometer
The carrier of soa receives different degrees of consumption, produces different refractivity, so that clock light is upper and lower through interferometer
Certain phase contrast is produced, because the light splitting ratio of b and the light splitting ratio of a are contrary, so b is to interferometer upper arm soa after arm soa
Modulating action is equal to the effect to interferometer underarm soa for a, and is functionally equivalent to a on interferometer to interferometer underarm soa
The effect of arm soa.So that after two-stage soa, clock optical interferometer upper and lower arm phase contrast is 0.Dividing through 3db bonder
Light is coupled with end, and destructive interference occurs, so that output signal pout is " 0 "；
When in two bundle injection lights, only one of which is " 1 ", that one-level for " 1 " carries out phase-modulation to clock light, due to
Xpm effect, upper and lower two-way produces certain phase contrast, still has non-zero phase contrast in output, so that avoiding after phase-shifter
Generation destructive interference is so that output signal is " 1 ".In view of the amplification of soa itself, because flashlight is put in the first order
It is easy to after big self phase modulation occur so that output is unstable in the second level, this programme is connected to work(between two-stage
Rate adjusting means, the PCU Power Conditioning Unit of the upper and lower arm of interferometer takes identical attenuation quotient, thus ensureing the interferometer of system
Upper and lower arm balance, so that output is stablized and ensure " 1 " pulse power roughly the same.
Fig. 3 is the result figure that implementation process of the present invention produces.
In Fig. 3, waveform 44 represents the power of input light a；Waveform 45 represents the power of input light b；Waveform 46 represents output light
Power.As can be seen that when the input signal of 40gbit/s is impulse form, output is complete well with a, b signal of input
Become the computing of logic XOR, and through power adjustments, the waveform of " 1 " code power of output and highly basically identical.In Fig. 2
In scheme, also can get with this figure substantially completely as output, therefore no longer show herein.
