Room-temperature operation of discrete-mode InGaAs-AlAsSb quantum-cascade laser with emission at ?=3.3 µm

Room-temperature operation of discrete-mode InGaAs-AlAsSb quantum-cascade laser with emission at ?=3.3 µm

Discrete-mode quantum-cascade lasers have been developed in the InGaAsAlAsSbInP materials system. For an uncoated 10-µm-wide ridge waveguide and 3000-µm-long cavity, the laser had a threshold current density J th of 4.2 kA·cm2 {Ith}=1.5 A)at 300 K with a slope efficiency of 80 mW/A. A stable single-...
