Theory of Guided Optical Mave Modulated by Magnetostatic Waves and Magneto-Optics Modulator

本文研究了具有任意磁化方向的静磁波调制的光调制理论和静磁波与光波相互作用。用耦合模理论研究TE(?)TM模随静磁波的变换,导出TE(?)TM模式转换效率表达式,给出理论上获得最大转换效率的条件。

Theory of optical modulated dy magnetostatic wave with an arbitrary direction, and the interaction of optical wave with magnetostatic waves are investigated. Using the mode coupling theory, the TE←→TM mode conversion with magnetostatic waves is examined. We derived the expression of the TE←→TM mode conversion efficiency. The conditions of maximum conversion efficiency are given in theory.
