Experimental demonstration of a Two-Dimensional Hole Gas (2DHG) in a GaN/AlGaN/GaN based heterostructure by optical spectroscopy
Loïc Méchin, François Médard, Joël Leymarie +5
The polarization discontinuity across interfaces in polar nitride-based heterostructures can lead to the formation of two-dimensional electron and hole gases. In the past, the obse…
Lasing in a ZnO waveguide: clear evidence of polaritonic gain obtained by monitoring the continuous exciton screening
Geoffrey Kreyder, Léa Hermet, Pierre Disseix +7
The stimulated emission of exciton-polaritons was proposed as a means of lowering the lasing threshold because it does not require the dissociation of excitons to obtain an electro…
Edge-emitting polariton laser and amplifier based on a ZnO waveguide
O. Jamadi, F. Reveret, P. Disseix +10
We demonstrate edge-emitting exciton-polariton (polariton) lasing from 5 to 300 K and amplification of non-radiative guided polariton modes within ZnO waveguides. The mode dispersi…
Long range correlations in a 97% excitonic one-dimensional polariton condensate
Aurélien Trichet, Emilien Durupt, François Médard +3
We report on the realization of an out-of-equilibrium polariton condensate under pulsed excitation in a one-dimensional geometry. We observe macroscopic occupation of a polaritonic…
LO-phonon assisted polariton lasing in a ZnO based microcavity
L. Orosz, F. Réveret, F. Médard +13
Polariton relaxation mechanisms are analysed experimentally and theoretically in a ZnO-based polariton laser. A minimum lasing threshold is obtained when the energy difference betw…
Fabrication and Optical Properties of a Fully Hybrid Epitaxial ZnO-Based Microcavity in the Strong Coupling Regime
L. Orosz, F. Réveret, S. Bouchoule +11
In order to achieve polariton lasing at room temperature, a new fabrication methodology for planar microcavities is proposed: a ZnO-based microcavity in which the active region is…
From Strong to Weak Coupling Regime in a Single GaN Microwire up to Room Temperature
A. Trichet, F. Médard, J. Zuniga-Perez +2
Large bandgap semiconductor microwires constitute a very advantageous alternative to planar microcavities in the context of room temperature strong coupling regime between exciton…
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…
