SGER: Self-Organizing Photorefractive Fiber Optic Demultiplexers

这笔赠款是为了研究和开发一种用于光纤通信系统的新型信号通道解复用器的工作实例。所提出的解复用器利用光折变元件的动力学来通过一组环形振荡器的模式之间的竞争性相互作用来分离通道。所提出的系统最显著的特性是它们通过自组织过程分离信道的能力：与大多数其他技术不同，这些光路只需要对输入信号了解很少；具体地说，人们不需要指定或知道传入光信道的频率(或波长)。根据它们的本质，光折变电路将倾向于跟踪信号源频率的漂移。此外，它们还可以容纳空间信息，因此可以应用于多模光纤通信系统。

This grant is to investigate and develop a working example of a new class of signal channel demultiplexers that are intended for use in fiber optic communication systems. The proposed demultiplexers employ the dynamics of photorefractive elements to separate the channels through a competitive interaction among modes of a collection of ring oscillators. The most remarkable property of the proposed systems is their ability to separate channels through a self- organizing process: unlike most other techniques, these optical circuits need to "know" very little about the incoming signals; in particular, one need not specify or know the frequency (or wavelength) of the incoming optical channels. By their very nature, the photorefractive circuits will tend to track drifts in the frequency of the signal source. They furthermore can accommodate spatial information and may therefore be applied to multimode fiber communication systems.
