This work was presented at the Nanofabrication Photonics Online Meetup, 16-18 May 2021. Template-assisted selective epitaxy enables the local integration of group III-V semiconductors on Si with high material quality for nanophotonic applications. Here we demonstrate evidence of room temperature lasing at 1530 nm for a monolithically integrated InGaAs whispering gallery mode cavity on Si with a thickness of 300 nm and a diameter of 1.5 µm. These devices can potentially be scaled down further by cladding them with metal.
