研究了一维光子晶体缺陷膜的滤波特性,重点研究了影响其滤波特性的因素及其影响规律。并对利用一维光子晶体技术开展多通道滤光片设计的可行性进行了研究。结果表明,利用光子晶体的滤波特性,可以设计出传统光学薄膜设计方法难以实现的多通道窄带滤光片,并根据实际需要,设计了一种双通道窄带滤光片。

The filtering characteristics of one-dimensional photonic crystal with defect mode was studied in detail,and the relevant influencing factors and rules have been emphasized. At the same time the possibility of designing multi-channel narrow band-pass filters using photonic crystals was demonstrated,the results show that it is possible to design multi-channel narrow filters using one-dimension photonic crystals. Finally a dual-channel narrow band-pass filter satisfying actual demand is designed and prepared.
