Low-threshold germanium laser for chip-scale LiDAR

Low-threshold germanium laser for chip-scale LiDAR

In this paper, we present our recent result on germanium lasers on silicon that operate at a low threshold. We will introduce our innovative strain engineering platforms that can create direct bandgap germanium nanowires by inducing >5% elastic tensile strain. Then, we will present our first expe...
