摘　　要：We have proposed and demonstrated hybrid Al Ga In As/Si Fabry–Pérot(FP) lasers, with the FP cavity facet covered by the p-electrode metal for enhancing mode confinement. Continuous-wave lasing is obtained at room temperature with a threshold current of 45 m A for the hybrid FP laser with a cavity length of 415 μm and a width of 7 μm. Near-field optical microscope images indicate an efficient output emission from the underneath evanescently-coupled silicon waveguide. Furthermore, single-mode lasing with a side-mode suppression-ratio of29 d B and a threshold current of 16 m A is realized for the 150 μm-long hybrid FP laser.We have proposed and demonstrated hybrid Al Ga In As/Si Fabry–Pérot(FP) lasers, with the FP cavity facet covered by the p-electrode metal for enhancing mode confinement.
