应用于全光网的取样布拉格光纤光栅数字波分复用器设计

未来全光网促进了新型光数字波分复用器interleaver的发展．基于取样光纤布拉格光栅的interleaver具有低插入损耗、多信道均匀反射峰和低色散等优点，特别适用于全光网的波长复用／解复用、插入／分离。为此提出了基于取样布拉格光纤光栅Interleaver的设计理论方法，合理设计其结构参数，并对其多波长滤波输出谱进行数值仿真，从而在〈50GHZ的DWDM窄带间隔实现均衡多波长滤波。这对光纤光栅在全光网的应用研究有一定的理论意义和工程应用参考价值。

The design of optical interleaver based sampled FBG for all - optical network

The demand for more bandwidth in future all-optical network has rapidly expanded the development of new optical components and devices for multi-channel optical interleaver.Optical interleaver based sampled FBG has the properties that of low insertion loss,reflection equalization for all channels,and low dispersions,etc.,so can be applied to the de-multiplexer or multiplexer in all-optical network.For this reason,it investigates the design theory of the interleaver based sampled Bragg grating by designing the grating's reasonable parameters and simulating the output results of the multi-wavelength filtering to demonstrate the feasibility of the equations muti-wavelengths filtering below the 50GHZ ITU-T channel spacing,which would be very meaningful for the researches and pratical use of the Bragg fiber grating for all-optical network..
