    This article presents a novel III-V on silicon laser. This work exploits the phenomenon that a passive silicon cavity, side-coupled to a III-V waveguide, will provide high and narrow-band reflectivity into the III-V waveguide: the resonant mirror. This results in an electrically pumped laser with a threshold current of 4 mA and a side-mode suppression ratio up to 48 dB

    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

    Experimental demonstration of a novel heterogeneously integrated III-V on Si microlaser

    In this work we present the first experimental demonstration of a novel class of heterogeneously integrated III-V-on-silicon microlasers. We first show that by coupling a silicon cavity to a III-V wire, the interaction between the propagating mode in the III-V wire and the cavity mode in the silicon resonator results in high, narrow band reflection back into the III-V waveguide, forming a so-called resonant mirror. By combining two such mirrors and providing optical gain in the III-V wire in between these 2 mirrors, laser operation can be realized. We simulate the reflectivity spectrum of such a resonant mirror using 3D FDTD and discuss the results. We also present experimental results of the very first optically pumped heterogeneously integrated resonant mirror laser. The fabricated device measures 55 mu m by 2 mu m and shows single mode laser emission with a side-mode suppression ratio of 37 dB
