Single photon interference between two modes originated from a single quantum dot
H. Kumano, S. Ekuni, H. Nakajima +5
Interference of a single photon generated from a single quantum dot is observed between two photon polarization modes. Each emitted single photon has two orthogonal polarization mo…
Precise measurements of electron and hole g-factors of single quantum dots by using nuclear field
R. Kaji, S. Adachi, H. Sasakura +1
We demonstrated the cancellation of the external magnetic field by the nuclear field at one edge of the nuclear polarization bistability in single InAlAs quantum dots. The cancella…
Hysteretic response of electron-nuclear spin system in single InAlAs quantum dots:Excitation power and polarization dependences
R Kaji, S Adachi, H Sasakura +1
We report the hysteresis of optically-pumped nuclear spin polarization and the degree of circular polarization of photoluminescence on the excitation power and electron spin polari…
Time domain optical manipulation of exciton and nuclear spin in a single self-assembled quantum dot
H. Sasakura, S. Adachi, S. Muto +3
We have demonstrated experimentally the manipulation of exciton and nuclear spins in a single self-assembled InAlAs/AlGaAs quantum dot. The oscill…
Optical diffraction spectroscopy of excitons in uniaxially-strained GaN films
Y. Toda, S. Adachi, Y. Abe +2
The degenerate four-wave mixing spectroscopy of uniaxially strained GaN layers is demonstrated using colinearly polarized laser pulses. The nonlinear response of FWM signal on exci…
Photon-spin qubit-conversion based on Overhauser shift of Zeeman energies in quantum dots
S. Muto, S. Adachi, T. Yokoi +2
We propose a new method to realize a conversion of photon qubit and spin qubit using the effective magnetic field created by the nuclear polarization known as Overhauser field. We…
