| 摘 要： | 利用传输矩阵法计算复周期结构的光子晶体的色散关系和滤波特性 ,并重点研究了含有缺陷的类似于谐振腔结构的光子晶体滤波特性.由于这种缺陷态复周期结构的可调参数多,人们很容易得到在红外波段1550 nm附近窄带滤波窗口,透过率可达到近90%,而窗口以外的透过率在0.02%以下.当改变中间夹层厚度、周期数及缺陷层数时,窄带滤波窗口的位置和带宽发生改变.因此,它在高速,长距离光通信中将有很好的应用. |

| Abstract: | The optical dispersion relation and the filtering properties on one-dimensional three component photonic crystal,espically the filtering properties of the photonic crystal with a defect layer have been studied by the transfer matrix method.Owing to its more adjustable parameters,the people can easily obtain narrow band transmission window at 1550 nm.The transmission can get to 90% inside the window,but only 0.02% outside the window.The width and the position of the window changes with the thickness of the defect layer、the number of periods and the number of defect layers.So it will have good application in the high-speed and long-range optical communication. |
| Keywords: | Photonic band gap Photonic crystal Narrow band filter Defect |
