  • Coherent optical manipulations of the Fundamental State in a single quantum dot
    Superlattices and Microstructures, 2008
    Co-Authors: Romain Melet, Valia Voliotis, Roger Grousson, Xue-lun Wang, Aristide Lemaître, Anthony Martinez
    Abstract:

    Abstract By means of an original all-optical experimental technique using microphotoluminescence in a waveguiding geometry, resonant coherent manipulation of quantum States in a single quantum dot becomes possible now. Resonant Rabi oscillation of the Fundamental exciton State in a single quantum dot has been realized. We present the results obtained on two different kinds of samples: InAs/GaAs self-assembled quantum dots and naturally formed GaAs quantum dots by thickness fluctuations.

  • First room temperature lasing from the Fundamental State of V-grooved quantum wire lasers
    Physica E-low-dimensional Systems & Nanostructures, 2000
    Co-Authors: Tae Geun Kim, Xue-lun Wang, R. Kaji, Mutsuo Ogura
    Abstract:

    Abstract Lasing from the ground State electron and heavy-hole-like transition of quantum wire (QWR) is demonstrated for the first time at room temperature, with an oxide-isolated V-grooved GaAs/AlGaAs triple QWR laser grown by flow-rate modulation epitaxy (FME). The lasing peaks at all temperatures (4– 300 K ) are in reasonably good agreement with both the photon energies of the peaks of the photoluminescence curves and the numerical calculation of the electronic sub-band energy States of the corresponding QWR structure. These results are considered to be responsible for the reduced heterointerface inhomogeneities (the Stokes shift ∼0.3 meV ) of the FME grown QWR, giving a low-loss wave guide in the QWR laser.

  • Resonant emission of a single InAs/GaAs quantum dot in a waveguiding configuration
    2006
    Co-Authors: R. Melet, Valia Voliotis, R. Grousson, Dimitri Roditchev, A. Lernaitre, A. Martinez, A. Ramdane
    Abstract:

    By means of confocal spectroscopy, optical properties of InAs/GaAs quantum dots embedded in a waveguide are studied. This new experimental configuration appears to be very promising in the framework of quantum computation in order to manipulate resonantly the Fundamental State of a quantum dot. Preliminary experiments which allow us to validate this new set-up have been performed. Micro -photoluminescence in a wave guiding configuration on a single QD and absorption measurements of an ensemble of dots are also presented.
