随着波分复用（wavelength-division multiplexing， WDM）传输设施部署的加快，下一步就是增加交叉连接来路由WDM信号。电光定向耦合器（dc）由于可以传递波分复用信号，因此非常适合这项任务。然而，DCs存在固有的串扰问题。消除串音一直是一个重要的设计问题。在本文中，我们展示了如何利用WDM信号的多波长特性来减少基于直流的光子开关系统中的串扰。
As the deployment of wavelength-division multiplexing (WDM) transmission facilities speeds up, the next step is to add cross-connects to route WDM signals. Electro-optical directional couplers (DCs) are well suited for the task since they can pass WDM signals. However, DCs suffer an intrinsic crosstalk problem. Removing crosstalk has been an important design issue. In this paper, we show how to take advantage of the multiple-wavelength characteristic of a WDM signal to reduce crosstalk in a DC-based photonic switching system.
