摘　　要：由亥姆霍兹方程得到的解,应用传输矩阵法,对加入缺陷的全介质多层光纤的径向滤波特性进行了计算和仿真,最终设计了一种加入缺陷的全介质多层光纤,通道间隔B约为0.8nm,可以很好地抑制四波混频效应,能很好地用于DWDM系统,也可以用于N通道波分复用—解复用滤波器。Using the Transfer Matrix Method have been studied the tiltering properties of the All- dielectric Multilayer Optical Fiber with defect, Wwning to its more adjustable parameters, the people can easily obtain narrow band transmission windows at 1 550 nm. The transmission can get to 99% inside the windows. The number of path and width change the place and refractive index of the defect layer. Finally, in succession a sort of All - dielectric Multilayer Optical Fiber was designed by us. So it will have good application in DWDM.
