Optoelectronic resonator neural networks

An associative memory is described which utilizes a hologram in a hybrid optoelectronic resonator. The nonlinear end mirrors of the resonator are two sets of video detectors and spatial light modulators which act as pseudoconjugators. The transformation properties of the end mirrors are programmable which allows the real-time selection of various associative pathways. An extension of the system to multilayer neural network models, in particular a backpropagation network, is also described.
