High-efficiency hybrid III–V/Si external cavity DBR laser for 3-µm SOI waveguides
We report a 9.5% wall-plug-efficient un-cooled external-cavity DBR laser built with a III-V-semiconductor reflective-SOA edge-coupled to an SOI waveguide containing a Bragg grating mirror. The hybrid laser is suitable for power efficient, CMOS-compatible optical transmitters.
