Abstract
In parallel optical information processing systems, three important specifications have to be fulfilled: (1) high space bandwidth product, (2) amplification for signal restoring, and (3) compensation for aberrations. The authors present a coherent optical feedback system which is capable of processing a large number of channels entirely in parallel. The system consists of a ring-resonator with a phase-conjugating mirror (PCM), formed by a BaTiO3-crystal, as an image amplifier. The aberration compensating property of optical phase-conjugation makes it possible to realize a feedback system with a space-bandwidth product up to >105, which would hardly be achievable otherwise. In addition, PCM-devices can be also used for the realization of different operations, such as phase visualization, coupling of channels, and image storage.
