Paper Abstract

This paper describes an optical holographic interconnection method for neural network implementations in which each connection weight is distributed among many angularly and spatially multiplexed photorefractive gratings. This approach greatly reduces crosstalk caused by the conical Bragg degeneracy associated with a single grating and permits the entire input plane to be used. Experimental results for an optical Perceptron network implemented using this method are presented.
