Abstract :
The authors report the first observation of intersubband electroluminescence in GaAs/AlGaAs-based quantum cascade structures. A 100 Å Al0.15Ga0.85As/Al0.4Ga0.6As well is employed to bridge the individual active regions to enhance the overall quantum efficiency, thus greatly simplifying the design and growth of quantum cascade structures
