The authors report for the first time an external cavity laser composed of a spot-size converted LD and a UV written waveguide grating, both integrated on Si. The laser operates in a single mode with a side-mode suppression of 37 dB. The threshold current is 12 mA and the average thermal coefficient is as low as -1.7 GHz.
