A heterogeneously integrated III-V-on-silicon laser is reported, integrating a III-V gain section, a silicon ring resonator for wavelength selection and two silicon Bragg grating reflectors as back and front mirrors. Single wavelength operation with a side mode suppression ratio higher than 45 dB is obtained. An output power up to 10 mW at 20 ⁰C and a thermooptic wavelength tuning range of 8 nm are achieved. The laser linewidth is found to be 1.7 MHz.
