中文摘要：
研究了以GCLM（the generalized Cantor-like multilayer）结构作为缺陷的光子晶体带隙结构和滤波特性.通过调整缺陷结构参量,可以得到通信波段1 300 nm～1 550 nm附近的窄带滤波窗口.滤波窗口透过率接近100%,而窗口以外的透过率在0.01以下.缺陷结构产生的Cantor分布,对光子晶体的透射特性产生很大影响,通过调整GCLM的结构,可以控制带隙的宽度及带隙中滤波窗口的数量和位置.和其他一维光子晶体相比,这种滤波特性能更好地应用在CWDM中.
英文摘要：
The band gap and filter properties of photo crystals with the generalized Canter-like multilayer （GCLM） defect are studied. By rectifying the parameters of the defect structure,Thin peak in band gap in the visible range is received. The transmission of the peak can achieve almost 100%, but the transmission out of the peak under 0. 01. The construction of GCLM systems according to the definite Cantor distribution brings improvements to the transmission properties. The wide of the band gap and the number and position of the peaks in band gap by rectifying the structure of GCLM can beem controlled. Compared with other one-dimensional photonic crystals,these filter properties may applied in CWDM better.
