摘　　要：利用传输矩阵方法,计算含缺陷模的一维光子晶体中缺陷模产生的窄透过带的滤波特性。结果得出,缺陷模介质的折射率越小,产生的超窄滤波带滤波性能越好;一维光子晶体的两基元介质折射率比值越大,产生的透过带越窄;缺陷插入一维光子晶体正中间产生的滤波效果最好。Filtering characteristics of one-dimensional photonic crystals with detect mold have been calculated by transfer matrix theories. The results are revealed as follows. The smaller the refractive index of dielectric of defect mold is, the better the performance of super narrow band optical filer is. The bigger the refractive index ratio of two primitive dielectrics of one-dimensional photonic crystals is,the narrower the transmission band is. When the defect mold is placed in the centre of one-dimensional photonic crystal,the filtering performance is the best.
