摘要：

We demonstrate monolithic 160-mu m-diameter rare-earth-doped microring lasers using silicon-compatible methods. Pump light injection and laser output coupling are achieved via an integrated silicon nitride waveguide. We measure internal quality factors of up to 3.8 x 10(5) at 980 nm and 5.7 x 10(5) at 1550 nm in undoped microrings. In erbium-and ytterbium-doped microrings we observe single-mode 1.5-mu m and 1.0-mu m laser emission with slope efficiencies of 0.3 and 8.4%, respectively. Their small footprints, tens of microwatts output powers and sub-milliwatt thresholds introduce such rare-earth-doped microlasers as scalable light sources for silicon-based microphotonic devices and systems.
