poster; Single-Wall Carbon Nanotubes (SWNTs) non-covalently fonctionalized with organic molecules have proven to be a very promising light-harvesting system. The goal is to combine the unique transport properties of nanotubes with the wide tunability

We present a general theoretical description of the extrinsic dephasing mechanism of spectral diffusion that dominates the decoherence dynamics in semiconductor quantum dots at low temperature. We discuss the limits of random telegraph and Gaussian s

We present the experimental evidence of giant optical anisotropy in single InAs QDs. Polarization-resolved photoluminescence spectroscopy in single QDs reveals a linear polarization ratio which fluctuates, from one dot to another, in sign and in magn

Polarization selective polariton scattering is demonstrated in quasi-one-dimensional microcavities. Due to the reduced symmetry in wire shaped cavities each polariton mode shows a polarization splitting into two modes polarized along and perpendicula

We report the observation of photoluminescence across the band gap of semiconducting carbon nanotubes encased in organic micelles at room temperature, for a large set of growth conditions and environment. The key point for observing luminescence is t

Angle-resolved optical spectroscopy is employed to investigate polariton dynamics under conditions of high excitations in CdTe-based microcavities. Time-resolved photoluminescence measurements under non-resonant excitation clearly show the suppressio

We used angle-resolved time-integrated four-wave mixing to study the pump dynamics in a II–VI semiconductor microcavity polariton parametric amplifier. The low-energy polariton dephasing time decreases at large angles when the excitonic reservoir b

We present a time-resolved experimental study of carrier dynamics in single wall carbon nanotubes (SWCNTs). This study is performed by means of pump–probe experiments in either a degenerate or a two-color configuration with a resonant excitation of

We report decoherence time measurements on the fundamental transition in single InGaAs quantum dots (QDs) by using a high-sensitivity Fourier transform spectroscopy on the photoluminescence signal arising from single QDs. We have investigated two sam

The linewidths of microcavity polariton modes are measured form reflectivity spectra at 10 K as a function of the detuning between exciton and cavity modes. The narrowing of the polariton features is described in the framework of the semiclassical ap
