Bunching visibility for correlated photons from single GaAs quantum dots
T. Kuroda, T. Belhadj, M. Abbarchi +11
We study photon bunching phenomena associated with biexciton-exciton cascade in single GaAs self-assembled quantum dots. Experiments carried out with a pulsed excitation source sho…
Optically monitored nuclear spin dynamics in individual GaAs quantum dots grown by droplet epitaxy
Thomas Belhadj, Takashi Kuroda, Claire-Marie Simon +6
We report optical orientation experiments in individual, strain free GaAs quantum dots in AlGaAs grown by droplet epitaxy. Circularly polarized optical excitation yields strong cir…
Photon correlation in GaAs self-assembled quantum dots
T. Kuroda, M. Abbarchi, T. Mano +11
We report on photon coincidence measurement in a single GaAs self-assembled quantum dot (QD) using a pulsed excitation light source. At low excitation, when a neutral exciton line…
Final-state read-out of exciton qubits by observing resonantly excited photoluminescence in quantum dots
K. Kuroda, T. Kuroda, K. Watanabe +4
We report on a new approach to detect excitonic qubits in semiconductor quantum dots by observing spontaneous emissions from the relevant qubit level. The ground state of excitons…
Self-assembly of laterally aligned GaAs quantum dot pairs
M. Yamagiwa, T. Mano, T. Kuroda +5
We report the fabrication of self-assembled, strain-free GaAs/AlGaAs quantum dot pairs which are laterally aligned in the growth plane, utilizing the droplet epit…
Optical transitions in quantum ring complexes
T. Kuroda, T. Mano, T. Ochiai +4
Making use of a droplet-epitaxial technique, we realize nanometer-sized quantum ring complexes, consisting of a well-defined inner ring and an outer ring. Electronic structure inhe…
