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

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology and can be used to create high-speed information processing devices and computer technology. The effect is achieved by the fact that an optical combiner and an optical transparency are introduced into the device, consisting of (m+1) sections with constant transmission functions equal to N^i-m, where i is the section number (i=0, ..., m), while the i-th input of the optical banner is the input of its i-th section, the i-th output is the output of the i-th section, and the i-th input of the N-ary (m+1)-bit optical DAC is the i-th input of the optical banner, the outputs of which are connected to the corresponding inputs of the optical combiner, the output of which is the output of the device.

EFFECT: simplification of the device and implementation of digital-to-analog conversion of N-ary codes.
