Paper Abstract

A fully parallel optical matrix-matrix multiplier is presented in this paper. Two N X N matrices are encoded on two tightly cascaded spatial light modulators (SLMs). One of the SLMs can be replaced by a light source array and a group of cylindrical lenses. Optical summation of all the outer product terms is performed by N lenses, which are arranged into a two-dimensional array to accommodate to the configuration of the SLMs used. Submatrices displayed on the SLMs are imaged by the corresponding lens in the lens array onto the output plane. Images of all the submatrices are superimposed and their intensities are added at the output plane to produce the multiplication result.
