Selectively configurable photonic logic device

A photonic logic gate selectively configurable to generate a logical output based on an intensity and a polarization of at least a first input light and a second input light, the photonic logic gate comprising:

• a managed input configured to receive at least a third input and a fourth input emitted from respective embedded lasers, the managed input further configured to output at least one of an A-polarized beam and a B-polarized beam based on a user-set intensity;
• said managed input including:
• a first filter assembly corresponding to polarization state ‘A’, communicatively coupled to the third input, the first filter assembly comprising a blocking polarizer, a rotator, and a passing polarizer arranged in succession;
• and a second filter assembly corresponding to polarization state ‘B’, communicatively coupled to the fourth input, the second filter assembly comprising a passing polarizer, a rotator, and a blocking polarizer arranged in succession;
• a first input path configured to selectively receive the first input light;
• a second input path configured to selectively receive the second input light, the second input path including an optoelectronic assembly comprising a first rotator, an absorptive linear polarizer, and a second rotator in series, the optoelectronic assembly configured to selectively control an intensity and a polarization of the second input light;
• a plurality of optical shutters configured to control passage of light;
• a plurality of absorptive linear polarizers;
• a plurality of liquid crystal rotators;
• a beamsplitter;
• a polarized beam splitter configured to separate input polarizations into a first separate path and a second separate path;
• a photosensitive circuit path, corresponding to the said first separate path and configured to receive a canceling polarization (B′), the photosensitive circuit path comprising:
• a photoresistor selectively configured to detect a target light intensity;
• and a rotator and an absorptive linear polarizer in series, positioned between the polarized beam splitter and the photoresistor;
• wherein the photoresistor is configured to, responsive to detecting the ‘B’-state polarization light intensity, trigger at least one of the plurality of optical shutters to selectively block or pass a beam in the said second separate path;
• a plurality of optical networking devices, positioned to overlap beams regardless of polarization;
• and an output system comprising a photodetector configured to receive beam ‘A’, wherein a logical output is generated based on an intensity of the received processed light meeting or not meeting a minimum brightness threshold at the photodetector.
