为了研究反射型一维磁光子晶体（1D-MPCs）在磁光（MO）应用中的潜力，进行了理论研究。计算结果表明，仅采用一层薄磁层的反射模一维磁光耦合器就能满足所需的磁光隔离器性能（反射率R>99%，克尔旋转角θ（K）= 45 °）。如果将介质多层膜和Al膜组合用作反射层，则满足隔离器要求的1D-MPC的结构比透射模式1D-MPC的结构简单得多。这对于实际的隔离器制造确实非常有吸引力。(C)2002年美国物理学会。
To investigate the potential of reflection type one-dimensional magnetophotonic crystals (1D-MPCs) for use in magneto-optical (MO) applications, theoretical studies were carried out. The calculations revealed that required MO isolator performance (reflectance R>99% and Kerr rotation angle theta(K)=45degrees) can be fulfilled with the reflection-mode 1D-MPC having only one thin magnetic layer. Provided that a dielectric multilayer film and Al film are combinatory used as the reflection layer, the structure of 1D-MPC satisfying the isolator requirements become much simpler than that of the transmission-mode 1D-MPC. This is indeed very attractive for actual isolator fabrications. (C) 2002 American Institute of Physics.
