VanderLugt correlator and neural networks

Abstract

Several experimental demonstrations of neural networks using coherent optics are demonstrated. An associative memory for word-break recognition and a learning machine for multicategory classification are discussed. Finally, a compact and robust coherent optical processor using a recently developed SELDA (surface emitting micro-laser diode array) is described. Although the applications are different, all these implementations are based on the VanderLugt correlator.
