Attojoule all-optical switching with a single quantum dot
Attojoule all-optical single quantum dot Quantum Physics
2011/8/17
Abstract: We experimentally investigate the dynamic nonlinear response of a single quantum dot (QD) strongly coupled to a photonic crystal cavity-waveguide structure. The temporal response is measured...
Ultrafast photon-photon interaction in a strongly coupled quantum dot-cavity system
photon-photon interaction coupled quantum dot-cavity system two weak light beams Quantum Physics
2011/8/17
Abstract: We study dynamics of the interaction between two weak light beams mediated by a strongly coupled quantum dot-photonic crystal cavity system. First, we perform all optical switching of a weak...

2011/8/17
Abstract: We discuss the fine-tuning of the optical properties of self-assembled quantum dots by the strain perturbation introduced by laser-induced surface defects. We show experimentally that the qu...

2011/8/4
Abstract: We have employed Bloch-wave engineering to realize submicron diameter ultra-high quality factor GaAs/AlAs micropillars (MPs). The design features a tapered cavity in which the fundamental Bl...
Quantum dot-cavity strong-coupling regime measured through coherent reflection spectroscopy in a very high-Q micropillar
Quantum dot-cavity strong-coupling regime coherent reflection spectroscopy high-Q micropillar
2010/11/18
We report on the coherent reflection spectroscopy of a high-quality factor micropillar, in the strong coupling regime with a single InGaAs annealed quantum dot. The absolute reflectivity measurement i...
Non-classical correlation of cascaded photon pairs emitted from quantum dot
Non-classical correlation cascaded photon pairs emitted quantum dot
2010/11/5
We studied the quantum correlation between the photon pairs generated by biexciton cascade decays of self-assembled quantum dots, and determined the temperature behavior associated with so-called sudd...
Quantum dot Rabi rotations beyond the weak exciton-phonon coupling regime
Quantum dot Rabi rotations weak exciton-phonon coupling regime
2010/10/21
We study the excitonic dynamics of a driven quantum dot under the influence of a phonon
environment, going beyond the weak exciton-phonon coupling approximation. By combining the
polaron transform a...
