Wavelength extension beyond 1.5 micrometer in symmetric InAs quantum dots on InP(111)A using droplet epitaxy
N. Ha, T. Mano, Y. -N. Wu +5
By using a C3v symmetric (111) surface as a growth substrate, we are able to achieve high structural symmetry in self-assembled quantum dots, which are suitable for use as quantum-…
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…
Notes on the bunching peak of g(2) functions for correlated photons from single quantum dots
T. Kuroda, C. Mastransdrea, M. Abbarchi +1
Second-order correlation functions for photon pulses associated with exciton-biexciton cascades are theoretically derived. A finite efficiency in photon detection and statistical d…
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…
