Abstract

This paper studies the coupling of light with intersubband excitations inthe case of multiple transitions. It is used a realistic input from a nonequilibrium many body solver in order to describe a microresonator with an active core region based on a successful quantum cascade laser design..

Keywords

Many-body theory, Quantum cascade lasers, Inter-subband transitions, Non-equilibrium distribution functions, Inter-sub-band antipolariton.
