Abstract

We report on high-power CMOS-compatible thulium-doped distributed feedback and distributed Bragg reflector lasers with single-mode output powers up to 267 mW and 387 mW, and slope efficiencies of 14% and 23% respectively. More than 70 dB side-mode suppression ratio are achieved for both lasers. This work extends the applicability of silicon photonic microsystems into the 2 mu m region.
