Properties of one-dimensional magnetophotonic crystals

Summary form only given. In recent years, Inoue and Fujii have studied theoretically and experimentally, the one-dimensional magnetophotonic crystal (1-D MPC) multilayer films composed of magneto-optical and dielectric materials. This 1-D MPC film exhibits an extremely large magneto-optical Faraday rotation due to the weak localization of light Such 1-D MPC film offers the possibility of realizing a rotation of 45/spl deg/ with a thickness of only several microns. The application from showing high transmittance (T) and large Faraday rotation (/sup /spl Theta///sub F/) to a variety of magneto-optical devices for optical communication (ex. film-based optical isolator) is expected. Therefore, we investigated on the possibility of the application to optical isolator (T>95%, /sup /spl Theta///sub F/=45/spl deg/) for the optical communication of 1-D MPC from the theory.
