Abstract
980nm InGaAs/GaAs separate confinement heterostructure (SCH) single quantum well (SQW) laser is grown by MBE. Photoluminescence and X-ray double crystal diffraction of the epilayer demonstrate good optical and crystalline quality. A QCW output power of 64.1W is achieved for a cm bar, which is limited by the current source. No thermal rollover in the output power is observed. The threshold current is 18.6A at 15°C. The slope efficiency is 1.14W/A with a corresponding power efficiency of 31.7%.
