Coherent optical manipulations of the fundamental state in a single quantum dot

7th International Conference on Physics of Ligh-Matter Coupling in Nanostructures (PLMCN7), Havana, CUBA, APR 12-17, 2007International audienceBy 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.
