Abstract :
We report on hybrid Si/III-V lasers with adiabatic coupling. The proposed architectures, based on adiabatic mode transformers, allow laser mode to experience maximal gain available in the III-V region while maintaining a high coupling efficiency (>;95%) to Si-waveguides. Hybrid Fabry-Pérot and racetrack lasers are presented.
