摘　　要：利用转移矩阵法分析具有线性和非线性缺陷层的一维光子晶体的传递函数并进行了数值模拟。由于缺陷层对周期性介质层的周期性破坏,带隙中产生了缺陷模。通过模拟仿真的结果,发现多缺陷层和非线性层都能够使带隙展宽,变得更加平坦。相比较之下,非线性层缺陷对带隙的作用更加强烈。The transfer characteristics of one-dimensional photonic crystal with linear and nonlinear defect layers are analyzed and simulated with a transfer matrix. Because of the periodic damage to the periodical medium by the defect layers, defect modes can appear in the band gaP. The simulation result shows that both a multi-defect layer and a nonlinear layer can broaden the width of the band gap and make it more flattened. By comparison, the defect in a nonlinear layer has more strong effect on the band gap.
