Paper Abstract

For the first time, we report on the 980 nm InGaAs/GaAs/AlGaAs strained quantum well lasers with window structure in regions near the laser facet fabricated by impurity-free vacancy diffusion for quantum well intermixing. In the fabricating procedure, SrF2 was used as a film suppressing the quantum well intermixing. 3 micrometers - stripe ridge waveguide lasers with window region of 25 micrometers at each end exhibit a high slope efficiency of 0.8 W/A and a threshold current of 20 mA. The characteristics are comparable with that of conventional lasers. Catastrophic optical mirror damage is not observed at thermal limited powers as high as 360 mW. Accelerated lifetesting at 100 mW and 50 degree(s)C shows devices to have good reliability.
