Optical associative memory based on an echo correlator.
A physical principle of the associative-memory optical implementation by using the photon-echo effect is proposed. The properties inherent in this phenomenon permit an optical scheme similar to the nonlinear holographic associative memory [Appl. Opt. 26, 1900 (1987)] to be considered. The associative-memory system based on the photon-echo effect uses a temporal selectivity instead of a spatial one.
