Abstract
The GaInAsSb-AlGaAsSb double quantum well lasers with an emission wavelength around 2.1μm, shown high quantum efficiency and high power conversion efficiency at continuous-wave power output. The threshold current density and the external quantum efficiency of the device were 130mA/cm2and 36.1%, respectively. The 15% maximum power conversion efficiency (PCE) were achieved from laser operating about 2.1μm wavelength.
