Journal ArticleDOI
Bose-Einstein condensation of exciton polaritons
Jacek Kasprzak,Maxime Richard,S. Kundermann,A. Baas,P. Jeambrun,Jonathan Keeling,Francesca Maria Marchetti,Marzena H. Szymańska,Régis André,Jl Staehli,Vincenzo Savona,Peter B. Littlewood,Benoit Deveaud,Le Si Dang +13 more
TL;DR: A comprehensive set of experiments giving compelling evidence for BEC of polaritons of bosonic quasi-particles are detailed, which indicate the spontaneous onset of a macroscopic quantum phase.
Journal ArticleDOI
High-temperature ultrafast polariton parametric amplification in semiconductor microcavities.
Michele Saba,Cristiano Ciuti,Jacqueline Bloch,V. Thierry-Mieg,Régis André,Le Si Dang,S. Kundermann,A. Mura,Giovanni Bongiovanni,Jl Staehli,Benoit Deveaud +10 more
TL;DR: 105 polaritons occupy the same quantum state during the amplification, realizing a dynamical condensate of strongly interacting bosons which can be studied at high temperature and could be exploited for high-repetition all-optical microscopic switches and amplifiers.
Journal ArticleDOI
Theory of the angle-resonant polariton amplifier
TL;DR: In this paper, a microscopic theory for the giant amplification from microcavities in the strong exciton-photon coupling regime is presented, providing excellent agreement with recent angle-resolved pump-probe experiments.
Journal ArticleDOI
Enhanced radiative recombination of free excitons in GaAs quantum wells.
TL;DR: Radiative properties of free excitons in a single GaAs quantum well are studied under resonant excitation and a radiative lifetime of 10.4 ps is deduced in the absence of dephasing mechanisms.
Journal ArticleDOI
Determination of intervalley scattering rates in GaAs by subpicosecond luminescence spectroscopy.
TL;DR: The importance of electron-electron scattering and inadequacy of a simple phonon-cascade model, even at a density as low as 5, is shown, and the electrons returning to the L act as a source of heating for the photoexcited plasma.
