Abstract

We propose and numerically analyze a novel sub-wavelength grating for the purpose of III-V/silicon integration. The design is based on different shapes of gratings in order to increase the lateral (or sideway) coupling. By using COMSOL® as the platform, the reverse V-grating design can have doubled percentage of optical field into the silicon grating region when compared to reference. However, the threshold gain of this design is still high and further optimization is needed.
