Demonstration of a picosecond optical-phase conjugation-based residue-arithmetic computation.

The use of the optical phase-conjugation (OPC) process for optical residue computation is proposed. By using an OPC-based parallel switching array, various optical position-coded residue-mapping units for carry-free addition, subtraction, and multiplication operations are described. Experimental results obtained with a picosecond mode-locked Nd3+:YAG laser are presented to support the proposal.
