摘要： 基于由传播矩阵方法获得的无源一维光子晶体结构的复透射系数公式,推导了一个描述单层介质膜频域透射率的简单解析表达式.该解析式清晰表明透射率随频率成周期振荡关系,类似于一个具有周期带隙的一维光子晶体结构,其振幅和周期可以直接由公式得出.讨论了利用其周期带隙实现密集波分复用系统中交错复用功能的可能性,分析了介质膜对超短光脉冲传播畸变的影响.

Abstract: A concise analytical expression for the transmittance of a homogeneous dielectric film is derived based on the transfer matrix method.It demonstrates a homogeneous oscillation in the transmittance as the function of the frequency.The amplitude and the period of the oscillation are also readily obtained by the expression analytically.Then,the behaviors of laserpulses propagating through a film under different conditions are discussed.All these properties are analogous to those of a one-dimensional periodic structure to some degrees.
