Optical implementation of a quadratic associative memory by using the polarization-encoding process

Abstract

As a higher-order associative memory of a neural network, the quadratic associative memory is implemented holographically by using the polarization-encoding process. The use of polarization encoding to represent sign in the quadratic associative memory tensor is made by twisted nematic liquid-crystal light modulators. Experimental results of retrieving the stored objects from an incomplete input are presented.
