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 2.35μ m exhibits a low-threshold current density at infinite cavity length of 83 A/cm² per QW under pulsed operation at room temperature. The internal loss α ⁱ and internal quantum efficiency η ⁱ of the laser are 17.5 cm^-1 and 15%, respectively.
