Spin temperature concept verified by optical magnetometry of nuclear spins
M. Vladimirova, S. Cronenberger, D. Scalbert +5
We develop a method of non-perturbative optical control over adiabatic remagnetisation of the nuclear spin system and apply it to verify the spin temperature concept in GaAs microc…
Polariton condensation in photonic molecules
Marta Galbiati, Lydie Ferrier, Dmitry D. Solnyshkov +9
We report on polariton condensation in photonic molecules formed by two coupled micropillars. We show that the condensation process is strongly affected by the interaction with the…
Ultra-low threshold polariton lasing in photonic crystal cavities
Stefano Azzini, Dario Gerace, Matteo Galli +5
The authors show clear experimental evidence of lasing of exciton polaritons confined in L3 photonic crystal cavities. The samples are based on an InP membrane in air containing fi…
Spontaneous formation and optical manipulation of extended polariton condensates
Esther Wertz, Lydie Ferrier, Dimitri Solnyshkov +9
Cavity exciton-polaritons (polaritons) are bosonic quasi-particles offering a unique solid-state system to investigate interacting condensates. Up to now, disorder induced localiza…
Exciton polaritons in two-dimensional photonic crystals
Daniele Bajoni, Dario Gerace, Matteo Galli +7
Experimental evidence of strong coupling between excitons confined in a quantum well and the photonic modes of a two-dimensional dielectric lattice is reported. Both resonant scatt…
Persistent currents and quantised vortices in a polariton superfluid
D. Sanvitto, F. M. Marchetti, M. H. Szymanska +10
Semiconductor microcavity polaritons in the optical parametric scattering regime have been recently demonstrated to display a new variety of dissipationless superfluid behaviour. W…
Optical bistability in a GaAs based polariton diode
Daniele Bajoni. Elizaveta Semenova, Aristide Lemaître, Sophie Bouchoule +5
We report on a new type of optical nonlinearity in a polariton p-i-n microcavity. Abrupt switching between the strong and weak coupling regime is induced by controlling the electri…
Sub-Terahertz Monochromatic Transduction with Semiconductor Acoustic Nanodevices
Agnes Huynh, Bernard Perrin, N. D. Lanzillotti Kimura +3
We demonstrate semiconductor superlattices or nanocavities as narrow band acoustic transducers in the sub-terahertz range. Using picosecond ultrasonics experiments in the transmiss…
Efficient dynamical nuclear polarization in quantum dots: Temperature dependence
B. Urbaszek, P. -F. Braun, X. Marie +4
We investigate in micro-photoluminescence experiments the dynamical nuclear polarization in individual InGaAs quantum dots. Experiments carried out in an applied magnetic field of…
Hole-LO phonon interaction in InAs/GaAs quantum dots
Vanessa Preisler, Robson Ferreira, Sophie Hameau +4
We investigate the valence intraband transitions in p-doped self-assembled InAs quantum dots using far-infrared magneto-optical technique with polarized radiation. We show that a p…
Dynamic nuclear polarization of a single charge-tunable InAs/GaAs quantum dot
Benoît Eble, Olivier Krebs, Aristide Lemaître +6
We report on the dynamic nuclear polarization of a single charge-tunable self-assembled InAs/GaAs quantum dot in a longitudinal magnetic field of 0.2T. The hyperfine interact…
