III–V/SOI vertical cavity laser with in-plane output into a Si waveguide

We experimentally demonstrate an optically-pumped III–V-on-SOI hybrid vertical-cavity laser that outputs light into an in-plane Si waveguide, using CMOS-compatible processes. The laser operates ∼1.49 µm with a side-mode suppression ratio of ∼27 dB and has a similar threshold as long-wavelength VCSELs.
