Paper Abstract

Anall-opticalprocessing ioop circuit, pumped entirely by semiconductor diode lasers, has been constructed and operated. Functional features include optically programmable logic, thresholding, and synchronization; these areachieved using threebistable interference filterdevices. Thecircuitispresently 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 i04. Circuit tolerancing is also described.
