Paper Abstract

Recording of dynamic nonlinear (chi) (2) hologram in glasses, based on the effect of photoinduced second harmonic generation is considered. Application of this phenomenon to generate a matrix of neurons for optical neuron network (NN) is proposed and studied by computer simulation. In the proposed model of NN a main laser radiation serves as a pump, and its second harmonic carries a signal. Modulation of the signal is achieved by both changing the signal amplitude and changing the relative phase between the signal and the pump. Computer simulation demonstrated that application of (chi) (2) hologram recording to create optical NN is possible. Also it was determined a structure of feedback in a NN that is able to the fast pattern recognition and can act as an associative memory.
