Paper Abstract

An all-optical processing loop circuit, pumped entirely by semiconductor diode lasers, has been constructed and operated. Functional features include optically programmable logic, thresholding, and synchronization; these are achieved using three bistable interference filter devices. The circuit is presently single-channel, however 15 x 15 capability of the devices has been demonstrated using Dammann holograms and array-to-array coupling of a pair of bistable plates; potential parallelism is in excess of lO. Circuit simulations and tolerancing are also described.
