The recent developments of nitride nanophotonics, based on photonic crystal membrane nanocavities and microdisk resonators, pave the way to a novel nanophotonic platform. Here we present two recent achievements: first we demonstrate the room-temperature operation of a nitride microlaser emitting in the deep UV spectral range (=275 nm) with...

The spatial dynamics of the formation of a polariton condensate under a tightly focused excitation is imaged through 2D near-field and far-field 2D tomography in a ZnO microcavity, up to room temperature. The modelling exhibits the role of the outwards polariton flux caused by the reservoir repulsion, that leads to a 3 to 10 fold increase of...

Dans le domaine de la nano-photonique, les matériaux semiconducteurs nitrures (GaN, AlN) présentent un intérêt grandissant en raison de leurs spécificités, et de leur complémentarité avec les filières déjà établies. Ces matériaux présentent en effet une plage de transparence large, du moyen infra-rouge à l'ultra-violet ; ils présentent aussi...
