RTCM算法在一维光子晶体缺陷模中的应用

利用RTCM算法研究一维光子晶体的缺陷模.研究了TE波和TM波入射时的情况,通过改变杂质层的光学厚度以及杂质层的折射率从而得出一些有重要指导意义的缺陷模特性.同时对有缺陷的一维光子晶体在窄带滤波器中的应用做了一定程度的探讨.结果表明:正入射时,TE波和TM波的透射率几乎相同,随着杂质层光学厚度的增加,透射峰数目增加,这有助于制作多道窄带滤波器.因此,有缺陷的一维光子晶体可以制作波分复用中的多道滤波器.

Applications in Defect Mode of One-dimensional Photonic Crystal with RTCM Arithmetic

The properties of defect mode in one-dimensional photonic crystal are studied with RTCM arithmetic when incidence angles of TE wave and TM wave are zero. We have gained some important characteristics of defect mode by changing optic thickness and refractive index of impure layer and have some carriedout explorations of filter application of defect mode of one-dimensional crystal. The results show that the transmissions of TE wave and TM wave are almost the same, and with the increase of optic thickness, the number of transmission peak increased. The features are useful in making multi-path filter. Therefore, the photonic with defect can be used to manufacture multi-path filters which are useful in WDM system.
