Abstract :
Continuous-wave operation of a terahertz quantum cascade laser is reported. The device is based on a chirped superlattice design consisting of a three quantum well gain region followed by a four quantum well relaxation/injection region, realised in the GaAs/Al0.15Ga0.85As material system. Optical output powers ranging from 410 μW at 10 K to 124 μW at 35 K, at an emission wavelength of 66 μm are obtained.
