| 摘 要： | 由磁光介质（M）和电介质（G）周期性排列构成的磁光光子晶体会出现很强的光 局域性，最近用它来实现磁光隔离器引起人们广泛的兴趣.给出了一种可用于计算 偏振光在各向异性介质传播问题的传输矩阵方法.并用该方法计算了对称多缺陷结构磁光多 层膜隔离器的光学性质，发现随着缺陷数目的增多，旋转角及透过率的频谱响应得到改善. 当缺陷增加到一定数目时，不需要额外的反射层即可实现反射型磁光隔离器的要求. 关键词：光隔离器磁光效应多层膜光子晶体

| Abstract: | Because of the localization of light, the magneto_optical (MO) photonic crystal, composed of magnetic and dielectric films periodically or quasi_periodically, can be used to manufacture the MO isolator. A transfer matrix method, suitable for computing the propagation of polarized light in anisotropic media, is described in detail in this paper. Using this method, we discuss the MO properties of a new type of MO isolator with multi_defect, and find that the spectra are broadened with increasing number of defects. A reflection_mode MO isolator without extra reflected layers is proposed when the number of defects is large enough. |
