Abstract

Fast parallel analog and digital optical computing operations are demonstrated by using an interferometric arrangement with photorefractive bismuth silicon oxide. Image subtraction, coherent weighted-image addition, exclusive OR/NOT, and OR optical gates are achieved by controlling the relative phase shifts of two phase-conjugate waves generated by degenerate four-wave mixing.
