OPTICAL DIGITAL-TO-ANALOG CONVERTER Russian patent published in 2018 - IPC G02F7/00 

FIELD: physics.

SUBSTANCE: optical combiner, optical Y-splitter, optical feedback waveguide are introduced into the optical digital-to-analog converter. The device input is the first input of the optical combiner, the output of which is connected to the input of an optical Y-splitter, the first output of which is connected to the input of an optical feedback waveguide, the output of which is connected to the second input of the optical combiner and the second output of the optical Y-splitter is the device output.

EFFECT: device is aimed at solving the problem of digital-to-analog conversion of serial optical codes with the speed, potentially possible for optical devices.
