摘要
为了解决空间光通信系统中调制功率受限的问题,以空间光通信为背景,利用准静态保角变换原理对具有高光损伤阈值的MgO∶L iNbO3集成波导外调制器进行了电极优化设计。对高功率激光在波导中的传播进行了仿真。基于仿真结果,分析了非线性效应所带来的影响,确定了器件最大输入光功率。该项研究对空间光通信等需要高速大功率激光调制技术的领域提供了有益的参考。
In order to break through the power restriction in IOC（ intersatellite optical communication）, the electrodes of MgO： LiNbO3 was optimally designed based on quasistatic conformal transformation theory in the background of IOC. The propagation of optical field with high input power was simulated. The effect of nonlinearity on modulator was analyzed and finally the maximum input power was determined. The research is significative for high power laser modulation field, such as IOC.
