Motion of spin polariton bullets in semiconductor microcavities
C. Adrados, T. C. H. Liew, M. D. Martin +7
The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied using time- and spatially-resolved spectroscopy. The switching is triggere…
Dynamics of a polariton condensate transistor switch
C. Anton, T. C. H. Liew, G. Tosi +6
We present a time-resolved study of the logical operation of a polariton condensate transistor switch. Creating a polariton condensate (source) in a GaAs ridge-shaped microcavity w…
Role of supercurrents on vortices formation in polariton condensates
C. Anton, G. Tosi, M. D. Martin +3
Observation of quantized vortices in non-equilibrium polariton condensates has been reported either by spontaneous formation and pinning in the presence of disorder or by imprintin…
Build up of off-diagonal long-range order in microcavity exciton-polaritons across the parametric threshold
R. Spano, J. Cuadra, C. Lingg +6
We report an experimental study of the spontaneous spatial and temporal coherence of polariton condensates generated in the optical parametric oscillator configuration, below and a…
Optical Anisotropy and Pinning of the Linear Polarization of Light in Semiconductor Microcavities
L. Klopotowski, M. D. Martin, A. Amo +6
We report a strong experimental evidence of the optical anisotropy in a CdTe-based microcavity: the polarization of light is pinned to one of the crystallographic axes independentl…
Influence of Trapping on the Exciton Dynamics of Al_xGa_1-xAs Films
A. Amo, M. D. Martin, L. Klopotowski +3
We present a systematic study on the exciton relaxation in high purity AlGaAs epilayers. The time for the excitonic photoluminescence to reach its maximum intensity (t_max) shows a…
Polarization Control of the Non-linear Emission on Semiconductor Microcavities
M. D. Martin, G. Aichmayr, L. Vina +1
The degree of circular polarization () of the non-linear emission in semiconductor microcavities is controlled by changing the exciton-cavity detuning. The polariton relaxatio…
Carrier and Light Trapping in Graded Quantum Well Laser Structures
G. Aichmayr, M. D. Martin, H. van der Meulen +6
We investigated the carrier and light trapping in GaInAs/AlGaAs single quantum well laser structures by means of time resolved photoluminescence and Raman spectroscopy. The influen…
Spin Dynamics of Cavity Polaritons
M. D. Martin, L. Vina, J. K. Son +1
We have studied polariton spin dynamics in a GaAs/AlGaAs microcavity by means of polarization- and time-resolved photoluminescence spectroscopy as a function of excitation density…
