摘　　要：利用传输矩阵法设计了蓝绿波段的光子晶体多峰滤波器,并研究了影响多峰滤波器的多种因素。结果表明:适当选取光子晶体结构参数,可将透射波段波长移到蓝绿光波段,设计出多峰光子晶体滤波器,适用于多路信号同时传输或双向同时传输。通过对双峰滤波器的优化,可设计出窄带双峰光子晶体滤波器,使多路信号之间干扰小,信噪比也得到改善。The transfer matrix method is used to design the two-way channel photonic crystal filters in the blue-green bands, and study the impact of multi-filter variety of factors. The results show that： The two-channel photonic crystal filters in the blue-green bands are designed when the appropriate parameters of photonic crystal structure are selected. And the filters are applied to multi-channel signal transmission or two-channel transmission at the same time. The two-channel photonic crystal filters in the blue-green bands can reduce the interference of the two-channel signal and improve the signal to noise ratio when the filters are optimized.
