Low threshold 2.72 /spl mu/m GaInAsSb/AlGaAsSb multiple-quantum-well laser

摘要

Ridge waveguide GaInAsSb/AlGaAsSb laser diodes, working continuous wave at room temperature with an emission wavelength of 2.72 /spl mu/m, are presented. A threshold current density as low as 356 A/cm/sup 2/ has been obtained for devices with 30 /spl mu/m stripe width and 1.5 mm cavity length in pulse mode at room temperature.
