摘要

研究了一种新的全光学非线性全息联想存储器结构[1]。采用多稳态、内容可寻址的空腔，一步完成图像比较、判别和读出。通过将光折变KNbO3晶体与向列液晶(NLC)组合在多光束反馈结构中，获得了所需的非线性过程。

All-Optical Associative Memory based on a Nonresonant Cavity with Image Bearing Beams

A new configuration of an all-optical, nonlinear holographic associative memory [1] is investigated. A multistable, content-addressable cavity is used, that performs image comparison, discrimination and read-out in one step. The required nonlinear processes are obtained by using a combination of a photorefractive KNbO3 crystal and a nematic liquid crystal (NLC) in a feedback configuration with several beams.
