Paper Abstract

An architecture for performing outer product Hopfield model associative memory (AM) by using the polarization encoding method has been proposed. It can realize AM with bipolar input vector and bipolar interconnection matrix. In the architecture, the multiplication of bipolar data is realized by rotating the polarization axis of the passed through light. The implementation uses only one optical electrical detector and needn't use any electric differential amplifiers, so it has high potentiality to be realized by all optics. Computer simulation and initial experiment results are given to demonstrate the proposed method.
