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.
