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 achieve using three bistable interference filter devices. The circuit is presently single-channel, however 15 × 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 104. Circuit tolerancing is also described.
