Abstract

一种光学滤波系统及方法，光学滤波系统包括第一准直器、第二准直器和反射式光学滤波器。光信号经第一准直器的第一端口（port 1）输入、第二端口输出，再经过反射式光学滤波器滤波后，经第一准直器的第二端口输入、第一端口（port 1）输出。经第一准直器的第一端口（port 1）输出的光信号输入第二准直器的第一端口（port 2）。光信号经第二准直器的第一端口（port 2）输入、第二端口输出，再经过反射式光学滤波器滤波后，经第二准直器的第二端口输入、第一端口（port 2）输出。光学滤波方法包括，光信号经准直处理后输入反射式光学滤波器，滤波并反射后再次经过准直处理；以上步骤至少重复两次。由此可以改善光滤波的性能。
