这笔赠款是为了调查和发展一个工作 一种新的信号通道类别的示例 用于光纤的多路分用器 光通信系统。 拟议 多路分解器采用动态的 光折射元件以分隔通道 通过各种模式之间的竞争性互动， 环形振荡器的集合。 最 所提出的系统的显著特性是 他们通过自我分离通道的能力 组织过程：与大多数其他技术不同， 这些光学电路需要知道的很少 关于传入的信号;特别是，一个需要 不指定或不知道频率（或波长） 进入的光通道。 由于其本身的 自然，光折变电路将倾向于 跟踪信号源频率的漂移。 此外，它还可以容纳空间 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.
