Abstract

We demonstrate the integration of long (2.4 mm) 1.3 μm etched facet quantum dot (QD) laser diodes into 7 μm deep recesses on an SOI wafer by micro transfer printing (μTP). Inverse tapered waveguide couplers were used to edge-couple the light from the QD laser to the 220 nm thick Si waveguide layer. Characterization exhibits that the QD lasers with 2 mm cavity length have threshold currents ~20 mA with output powers above 10 mW at 80 mA. A waveguide-coupled power of ~1mW was obtained.
