Abstract

An all-optical parity checker and parity bit generator circuit is proposed, in which optical non-linear materials are used as switching devices. High-speed (above GHz) logic operations can be achieved by this all-optical circuit that is tremendously fast than its equivalent electronic counterpart. Here these circuits are used to check the errors in optical data through a transmission line.
