The research on GaN lasers aims for a continuous reduction of the lasing threshold. An approach to achieve it consists in exploiting stimulated polariton scattering. This mechanism, and the associated polariton lasers, requires an in-depth knowledge

The physics of gain in interband semiconductor lasers is mostly discussed in terms of population inversion for electrons and holes and the associated Bernard-Durrafourg condition. Due to the reciprocity between the processes of absorption and stimula

International audience; Planar microcavities filled with active materials containing excitonic resonances host radiative exciton-polariton (polariton) modes with in-plane wave vectors within the light cone. They also host at least one mode that is gu

We report on a study of the excitonic properties of GaN/AlxGa1-xN quantum well samples using continuous-wave reflectivity and photoluminescence measurements. Weak excitonic signals superposed to large oscillations resulting from the interferences in
