应用于全光网络的取样布拉格光纤光栅Interleaver设计

摘要

基于取样光纤布拉格光栅(SFBG)的光Interleaver能将一路光信号解复用为两路奇偶波长信号,具有插入损耗低、各信道反射率均匀和低色散等优点,特别适用于未来全光DWDM中波长复用/解复用、插入/分离.为此介绍了取样光栅Interleaver的基本设计理论,给出了设计实例,对取样光栅Interleaver等光器件的实用化有一定的参考意义.%Optical interleaver based on sampled FBG (fiber Bragg grating) can separate optical signals into two branches. Each of the branches is composed of odd or even channels only. This optical interleaver has the merits such as low insertion loss, reflection equalization for all channels, and low dispersions, etc., so it can be applied to the de-multiplexer or multiplexer in DWDM systems. For this reason, the basic design theory and some design examples of optical interleaver based on SFBG are investigated, which is helpful for the interleaver's practical applications.
