Transport of dipolar excitons in (Al,Ga)N/GaN quantum wells
F. Fedichkin, P. Andreakou, B. Jouault +8
We investigate the transport of dipolar indirect excitons along the growth plane of polar (Al,Ga)N/GaN quantum well structures by means of spatially- and time-resolved photolumines…
Laser emission with excitonic gain in a ZnO planar microcavity
Thierry Guillet, Christelle Brimont, Pierre Valvin +8
The lasing operation of a ZnO planar microcavity under optical pumping is demonstrated from T=80 K to 300 K. At the laser threshold, the cavity switches from the strong coupling to…
High quality factor nitride-based optical cavities: microdisks with embedded GaN/Al(Ga)N quantum dots
Meletios Mexis, Sylvain Sergent, Thierry Guillet +9
We compare the quality factor values of the whispery gallery modes of microdisks incorporating GaN quantum dots (QDs) grown on AlN and AlGaN barriers by performing room temperature…
Low temperature reflectivity study of ZnO/(Zn,Mg)O quantum wells grown on M-plane ZnO substrates
Luc Beaur, Thierry Bretagnon, Christelle Brimont +5
We report growth of high quality ZnO/Zn0.8Mg0.2O quantum well on M-plane oriented ZnO substrates. The optical properties of these quantum wells are studied by using reflectance spe…
Relaxation and emission of Bragg-mode and cavity-mode polaritons in a ZnO microcavity at room temperature
Stéphane Faure, Christelle Brimont, Thierry Guillet +12
The strong coupling regime in a ZnO microcavity is investigated through room temperature photoluminescence and reflectivity experiments. The simultaneous strong coupling of exciton…
Comparison of strong coupling regimes in bulk GaAs, GaN and ZnO semiconductor microcavities
Stéphane Faure, T. Guillet, P. Lefebvre +2
Wide bandgap semiconductors are attractive candidates for polariton-based devices operating at room temperature. We present numerical simulations of reflectivity, transmission and…
