We describe an optical interconnection method based on self-pumped phase-conjugate mirrors in which each connection weight is distributed among many angularly and spatially multiplexed gratings. This approach greatly reduces cross talk caused by the conical Bragg degeneracy associated with a single grating and permits the entire input plane to be used. Applications to optical neural networks are described.
