The main candidate to be a ubiquitous high power THz source is the intersubband-based quantum cascade laser (qcl). In this review we start by discussing current challenges for THz intersubband qcl development from a microscopic point of view. Next we evolve to a discussion about the search for new mechanisms and structure designs that can lead to(More)
The author discusses the main goals and recent achievements of MPNS COST ACTION MP1204, TERA-MIR Radiation: Materials, Generation, Detection and Applications, whose main objectives are to advance novel materials, concepts and device designs for generating and detecting THz and Mid Infrared radiation using semiconductor, superconductor, metamaterials and(More)
In this paper, we calculate the luminescence of the dilute quaternary InAs<sub>1-x-y</sub>N<sub>x</sub>Sb<sub>y</sub> semiconductor using a microscopic approach. The theory starts with the band anticrossing model applied to both conduction and the valence band to generate input for analytical approximations that lead to luminescence spectra, including(More)
