Abstract : Wave mixing and holographic recording in photorefractive media have been used to perform parallel matrix-vector multiplication. Although the technique can be extended to perform parallel matrix-matrix multiplication, the implementation requires critical alignment of the matrix elements. In this paper, we propose to demonstrate a novel technique to perform parallel matrix-matrix multiplication which uses the simultaneous formation of multiple gratings in a photorefractive crystal.
