Growth of quantum cascade lasers based on strain-compensated InxGa1−xAs/InyAl1−yAs and operating at a wavelength shorter than 4 μm is reported. Pulsed mode operation of these lasers up to T=280 K is reported with a high T0. Continuous wave powers as high as 120 mW are reported at cryogenic temperatures (15 K).
