The Terahertz domain (THz), situated between the visible and microwave energy range, turns out to be very promissing in terms of applications. However its application potential is not fully used because of the lack for compact sources able to cover a

Quantum cascade lasers (QCLs) are powerful terahertz (THz) and mid-infrared (MIR) sources. Their emission relies on intersubband transitions i.e. transitions between confined electronic states in the conduction band of these semiconductor nanostructu
