研究了含有Kerr非线性介质的一维光子晶体的传播特性,在处理非线性层部分时,创立了一种新的算法,此方法可以方便而精确地模拟含Kerr介质的光子晶体的传输行为。并得出了与子层逆向递推传输矩阵相一致的结果,与之相比,同时具有简单、快速、易懂的特点。
The propagation characteristics of one-dimensional photonic crystal with inhomogeneous Kerr medium were studied, and a new algorithm for dealing with nonlinear part of the layer was created. It's very convenient to simulate the transfer behavior of one-dimensional Kerr medium. Optical bistable switching of 1D photonic crystal with Kerr defect was investigated by this method, and the results were well in line with those of sub-layer recursive reverse transfer matrix method. Moreover, the new method exhibits simple rapid and easy-to-understand .
