Abstract
We discuss an optical interconnection method for neural networks based on mutually pumped phase conjugation in a photorefractive crystal. Cross talk due to Bragg degeneracies is reduced by storing each connection weight in a continuum of angularly and spatially multiplexed volume gratings.Keywords
