摘要
设计了一种单块晶体集成的n×n纵横开关(Crossbar)网络。通过综合考虑晶体的双折射和全内双反射现象,以及晶体的电光效应,将构成n×n纵横开关网络的所有单元器件都集成到一块具有电光效应的双折射晶体上。同时,给出了该网络的控制算法,通过对开关工作状态的控制,可以实现任意输入输出通道之间的无阻塞连接。这种单块晶体集成的纵横开关网络具有能量损耗低、无阻塞、易安装、抗干扰等优点,适合于全光网络发展的需要。
An integrated n×n crossbar network is designed, which consists of 2×2 switches and crossbar interconnections. Considering both the phenomena of double refraction and internal double reflection, and the electro-optic effect in a crystal, all elements of n×n crossbar network are integrated in one birefringent crystal slab with electro-optic property. A control algorithm of the crossbar network is discussed, which may control the nonblocking interconnection between any input-output pair. The integrated crossbar network with low energy loss, nonblocking, is easy to assemble, insensitive to environment, well suited for use in optical networks.
