Spectroscopic studies of optical and electronic processes in quantum cascade lasers
In this thesis, two sets of quantum cascade lasers were studied. The first set is three Ga0.3In0.7As/A1As(Sb)/lnP strain compensated QCLs emitting at 3.3 μrn at room temperature. The three QCL samples have the same active region design but differ in their waveguide doping. The losses within the samp...
