摘要:	The electrically driven short-wavelength infrared semiconductor laser using InP-based InGaAs/GaAsSb W-type quantum wells (QWs) is investigated. Using Sb-free separate confined layer and engineered QWs, the laser lasing at 2.35 mu m exhibits a low-threshold current density at infinite cavity length of 83 A/cm(2) per QW under pulsed operation at room temperature. The internal loss alpha(i) and internal quantum efficiency eta(i) of the laser are 17.5 cm(-1) and 15%, respectively.
