OPTICAL COMPARATOR Russian patent published in 1994 - IPC

FIELD: specialized computer technology. SUBSTANCE: two input information and two control splitters are introduced into the comparator. Each information splitter has input to be input of the comparator; the information splitter has group of waveguide branches optically coupled together. The branches splits to two branches more in such a manner, that any subsequent branch of the group has to be the second branch of previous one. The first branches of both groups have to be optically coupled waveguides provided with corresponding two branches of the first control splitter. Like branches of both information splitters have inputs connected. Output parts of all the branches of the first information splitter have to be optically coupled waveguides with branch of the second control splitter, which has output to be output of the comparator. EFFECT: improved reliability of operation; improved efficiency. 1 dwg
