1.6 µm continuous-wave lasing from InAs/AlGaInAs quantum dash micro-disk lasers grown on (001) silicon

We present preliminary results of InAs/InAlGaAs quantum dash (QDash) micro-disk lasers directly grown on (001) silicon. Continuous-wave (CW) single-mode lasing at 1.6 μm under optical pumping is demonstrated with an average threshold of 0.96 mW.
