基于光子晶体的禁带特性，设计出一种复周期结构的一维光子晶体多通道滤波器。利用传输矩阵法，并通过Matlab 编程仿真，甄选出两种最合适的光子晶体材料，并确定其结构参数。仿真结果表明，所设计的一维光子晶体多通道滤波器，在目前主要通信波长范围内可得到多个高透射窗口，且通过调节可以得到需要数量的信道。

Based on the bandgap properties of photonic crystals, an one- dimensional photonic crystals multichannel filter with a comlicated periodic structure is designed. Using transfer matrix method, and through the Matlab simulation, two appropriate photonic crystal materials are selected and its structural parameters are determined. Simulation results show that the filter can obtain multiple high- emitting windows in the current main communication wavelength range, and the required number of channels be regulated.
