与单纯的磁光晶体相比 ,由磁光介质与电介质周期性或准周期性排列构成的一维磁光光子晶体能够显著增强磁光效应 ,可以用于实现小尺度的磁光隔离器 ,从而大大减小器件的尺寸 .给出更为一般的可用于求解斜入射情况下偏振光在各向异性介质中传播时的传输矩阵方法 ,并用这种方法在波长为 1 0 5 3μm处 ,针对两种“三明治”型的反射磁光多层膜隔离器的结构 ,具体讨论了器件应用时入射角度及工艺制作时膜层制备厚度对它们工作稳定性的影响 .发现中心磁光介质夹层较厚的结构具有膜层数目少、工作稳定性好的优点 .
Compared with the pure magneto-optical crystal, the one-dimensional magneto-optic photonic crystal composed of periodic or quasi-periodic arrangement of the magneto-optical medium and the dielectric can remarkably enhance the magneto-optical effect and can be used to realize a small-scale magneto-optical isolator The size of the device is greatly reduced.A more general transmission matrix method is given for the propagation of polarized light in an anisotropic medium under oblique incident conditions.At the same time, The structure of “Sandwich” type reflective magneto-optical multi-layer film isolator is discussed in detail, and the effect of the incident angle of the device and the thickness of the prepared film on their work stability are discussed in detail. Structure with a small number of films, the advantages of good work stability.
