Abstract

An ultrafast parallel optical phase conjugation (OPC) effect for the use of optical digital computation is described. Using spatially encoded logic values, symbols, optical binary, multiple-varied logic, symbolic, as well as interconnect operations are performed. The proposed processors are experimentally verified with a 32-ps pulse Nd³⁺:YAG laser. Based on these elemental processors, an OPC-based optical digital computer architecture is proposed. Using this architecture, iterative arithmetic and symbolic computation examples are presented. Some of the OPC computer performance factors, such as real-time encoding, signal amplification, etc. are also discussed.
