Hybrid III-V/silicon micro-lasers based on resonant cavity reflectors

We present a novel approach to design compact, single mode, hybrid 111-V/silicon microlasers. At both ends of the 111-V laser cavity, silicon gratings are operated in a resonant regime to allow high reflection over a short distance. We have verified this technique numerically andfound that, for a thick bonding layer of350 nm, more than 93% reflection can be obtained over a distance of less than 20 pm
