| 摘 要： | 理论计算表明，与垂直静磁场情形相比，斜向静磁场可以明显增强磁性薄膜波导中的法拉第效应，同时会引起静磁波共振频率和带宽等许多静磁波特性的变化.合理利用这些变化特性，可望大幅度提高导波光的衍射效率，改善磁光波导器件的特性.

| Abstract: | It is shown by calculation that,in contrast to the usual situation of a perpendicular bias magnetic field,an inclined bias magnetic field enhances Faraday effect,and leads to modification to the properties such as the resonant frequency and the bandwidth of magnetostatic wave in magnetic waveguide.Making appropriate use of such properties,it is possible to greatly increase the magnetooptic (MO) Bragg diffraction efficiency and to improve the characteristics of guided-wave MO Bragg devices. |
