Demonstration of a novel single-mode hybrid silicon microlaser

摘要

We present the first experimental demonstration of a novel class of hybrid III–V on silicon microlasers. This new type of laser revolves around the concept of resonant mirrors: two silicon cavities, directly coupled to the III–V laser mesa, provide high, narrow band reflection over a short distance. This results in a device that measures only 55 µm by 2µm and shows single-mode laser emission with a SMSR of 39 dB.
