摘　　要：采用传输矩阵的方法研究带缺陷的一维光子晶体 ,缺陷的引入使得原来不透电磁波的禁带中 ,出现了缺陷模 ,计算表明缺陷模的频率与透过率随着不同介电常量、不同几何结构以及掺杂的晶体结构而改变 ,频率位于带隙中的光子受到抑制 ,所以掺杂光子晶体的信道间信号串扰必然受到抑制 ,由此形成无序光子晶体密集波分复用 (DWDM )光通信系统 .With the numerical value researching in such impure one-dimensions photo crystals by the method of optic transmitting matrix, importing the disfigurement makes the disfigurement model in the ban strap of formerly no appear Hertzian waves,account the different electrical constancy ,different geometry structure and the structure of impure crystals , As the photo crystals with its frequency in the gap of the strip is restrained ,the interference of signals in the channel with impure photo crystals are sure to be restrained ,hence ,the density wave division multiplexing optic communication System (DWDM)of no sequence photo crystals comes into being .
