Hybrid Si/III-V Fabry-Perot lasers based on adiabatic mode transformers

We report the first Si/III-V Fabry-Perot laser based on adiabatic mode transformers. The investigated device operates under quasi-continuous wave regime. The room temperature threshold current is 100 mA, the side mode suppression ratio is as high as 20dB, and the fiber-coupled output power is ∼7mW.
