Ridge waveguide GaInAsSb/AlGaAsSb laser diodes, working continuous wave at room temperature with an emission wavelength of 2.72 μm, are presented. A threshold current density as low as 356 A/cm2 has been obtained for devices with 30 μm stripe width and 1.5 mm cavity length in pulse mode at room temperature.
