The basic building blocks of an interconnection network are the switching elements. We examine two optical implementations for a basic switching element: (1) ferroelectric liquid-crystal light valves and (2) Fabry-Perot étalons. For these two examples we report a trade-off between the size, i.e., the number of input and output channels, and the switching speed. We speculate that it may be a general property of optical switching elements that size and speed cannot be optimized simultaneously.
互连网络的基本构建块是交换元件。我们研究了一种基本交换元件的两种光学实现方式：（1）铁电液晶光阀和（2）法布里 - 珀罗标准具。对于这两个例子，我们报告了在尺寸（即输入和输出通道的数量）和开关速度之间的权衡。我们推测，尺寸和速度不能同时优化可能是光学开关元件的一个普遍特性。
