磁光空间光调制器（MOSLM）可以对光波前进行幅度、相位和偏振的高速调制。然而，过去的MOSLM需要大的驱动电流。为了克服这一缺点，我们研制了一种由电场和外磁场驱动的PZT层MOSLM。电压驱动的MOSLM的有效结构也进行了研究，使用有限元模拟。磁光子晶体由介质镜和磁缺陷层组成，可以大大增强磁光效应。对应力分布较好、法拉第旋转角较大的MPC结构进行了应力分布计算。
The magneto-optic spatial light modulator (MOSLM) can modulate amplitude, phase, and polarization of optical wave front at high speed. However, past MOSLM requires large driving current. To overcome the disadvantage, we have developed the MOSLM with PZT layer driven by electric field and external magnetic field. The effective structure of the voltage-driven MOSLM was also investigated using finite element simulation. A magneto photonic crystal(MPC), which consists of dielectric mirror and magnetic defect layer, can largely enhance MO effect. The stress distribution calculation of MPC structure with good stress distribution and a large Faraday rotation was done based on a structure of a thin MO film.
