OPTICAL ANALOG-TO-DIGITAL CONVERTER Russian patent published in 2021 - IPC G02F7/00 

FIELD: computing technology.

SUBSTANCE: invention relates to specialized computing technology and can be used to create high-speed information processing devices and computer technology in control and communication systems that provide information processing in the gigahertz range. The optical analog-to-digital converter has a source of coherent radiation, a voltage source, (K=M+1) - an output optical splitter, M optical transparencies (M = 2^N-1, N is the converter capacity), M optical Y-combiners, M optical inverters, an electro-optical amplitude modulator, an optical phase modulator, an M-output optical splitter, M N-output optical splitters, N M-input optical combiners, N photodetectors. Moreover, each inverter contains a resistor, a photodiode, the input of which is the information input of the optical inverter, and an LED connected in parallel with the photodiode in such a way that the cathode of the photodiode is connected to the anode of the LED, the output of which is the output of the optical inverter, and through a series-connected resistor, the cathode of the photodiode is connected to the positive electrode of the power input of the optical inverter, and the anode of the photodiode is connected to the negative electrode of the power input of the optical inverter connected to the output of the voltage source.

EFFECT: invention increases the speed of conversion into a positional binary code of electrical analog signals.
