摘要

我们演示了一种自组织光折变电路对光信号进行解码。该电路是一对具有光折变增益和合作模式与竞争模式相互作用的环形谐振器。当使用包含两个光载波频率的空间多模光束作为泵浦时，谐振器自组织使得每个频率在空间分离的环中振荡。使用双晶BaTiO3谐振器的初步结果显示，在两个输出处的对比度优于20:1。

A Self-Organizing Photorefractive Frequency Decoder

We demonstrate a self-organizing photorefractive circuit which decodes optical signals. The circuit is a pair of ring resonators with photorefractive gain and cooperative and competitive mode interactions. When a spatially multimode beam containing two optical carrier frequencies is used as the pump, the resonator self-organizes such that each frequency oscillates in spatially separate rings. Initial results, with a two crystal BaTiO3 resonator, show a contrast ratio of better than 20:1 at the two outputs.
