Abstract
Continuous wave and above liquid-nitrogen temperature operation of MBE grown terahertz quantum cascade lasers based on the In0.53Ga0.47As/In0.52Al0.48As/InPIn0.53Ga0.47As/In0.52Al0.48As/InP material system are reported. Samples investigated used a bound-to-continuum active region design with a single or double quantum well injector at the wavelength λ≈80μm. A precise flux calibration and a modified injector design resulted in a maximum operating temperature in continuous wave and pulsed mode of 63 and 87 K and an optical output power of 4 mW at 10 K.
