这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )

说明：  采用多相滤波结构，可利用多个阶数较低的滤波来实现原本阶数较高的滤波，而且每个分支滤波器处理的数据速率仅为原数据速率的I/D，这为工程上高速率实时信号处理提供了实现途径。(By using polyphase filter structure, the original higher order filtering can be achieved by using multiple lower order filters, and the data rate processed by each branch filter is only I/D of the original data rate, which provides a way to realize high-speed real-time signal processing in engineering.)
