Paper Abstract

A new architecture for performing outer product Hopfield Model associative memory has been proposed by using a polarization encoding method. In the architecture, multiplication is performed by rotating the polarization of the transmitted light, and optical associative memory with bipolar binary inputs and bipolar analog interconnect weights can be realized. Also no electronic differential amplifiers need to be used in the architecture, so it may be realized by all optics.
