An external cavity tunable laser, which is based on a silicon hybrid micro-ring resonator, is demonstrated. The heat isolate grooves around the rings effectively cuts off temperature crosstalk. Experimental results have shown that the output power of this device can reach 15.5dBm, with a linewidth less than 130 kHz. The tuning range is more than 57nm in C-band with 60 dB side mode suppression ratio (SMSR).
