Ridge polariton laser: different from a semiconductor edge-emitting laser
H Souissi, M Gromovyi, T Gueye +11
We experimentally demonstrate the difference between a ridge polariton laser, and a conventional edge-emitting ridge laser operating under electron-hole population inversion. The h…
Dynamical control over the confinement of spatially indirect excitons in electrostatic traps of GaAs coupled quantum wells
Mussie Beian, Suzanne Dang, Mathieu Alloing +6
We study spatially indirect excitons confined in a 10 m wide electrostatic trap of a GaAs double quantum well. We introduce a technique to control the amplitude of the electric…
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…
Temporal Coherence of Spatially Indirect Excitons across Bose-Einstein Condensation: the Role of Free Carriers
Romain Anankine, Suzanne Dang, Mussie Beian +4
We study the time coherence of the photoluminescence radiated by spatially indirect excitons confined in a 10 m electrostatic trap. Above a critical temperature of 1 Kelvin, we…
Quantized Vortices and Four-Component Superfluidity of Semiconductor Excitons
Romain Anankine, Mussie Beian, Suzanne Dang +6
We study spatially indirect excitons of GaAs quantum wells, confined in a 10 microns electrostatic trap. Below a critical temperature of about 1 Kelvin, we detect macroscopic spati…
Spectroscopic Signatures for the Dark Bose-Einstein Condensation of Spatially Indirect Excitons
Mussie Beian, Mathieu Alloing, Romain Anankine +4
We study semiconductor excitons confined in an electrostatic trap of a GaAs bilayer heterostructure. We evidence that optically bright excitonic states are strongly depleted while…
Exciton/plasmon polaritons in GaAs/GaAlAs heterostructures near a metallic layer
J. Bellessa, C. Symonds, C. Meynaud +5
We report on the strong coupling between inorganic quantum well excitons and surface plasmons. For that purpose a corrugated silver film was deposited on the top of a heterostructu…
