论文摘要
我们通过同时填充因子和周期来设计一个聚焦的光栅耦合器。除了集中在输入波导的平面外,总长度小于70μm,曲率的进一步插值还可以从聚焦到远离光栅表面150μm的纤维中的平面。该设计是针对绝缘体波导(例如Gainp)的新型半导体提出的。耦合效率是根据大约45%的二维模拟计算得出的。
We design a focusing grating coupler by a simultaneous apodization of the filling factor and the period. In addition to in plane focusing to the input waveguide providing a total length of less than 70μm, a further apodization of the curvature allows out of plane focusing into a fiber set 150μm away from the grating surface. The design is proposed for novel semiconductor on insulator waveguides such as GaInP. The coupling efficiency is calculated from two dimensional simulation which is about 45%.
