Robust quantum dot state preparation via adiabatic passage with frequency-swept optical pulses
C. -M. Simon, T. Belhadj, B. Chatel +8
The energy states in semiconductor quantum dots are discrete as in atoms, and quantum states can be coherently controlled with resonant laser pulses. Long coherence times allow the…
Impact of heavy hole-light hole coupling on optical selection rules in GaAs quantum dots
Thomas Belhadj, Thierry Amand, Alejandro Kunold +8
We report strong heavy hole-light mixing in GaAs quantum dots grown by droplet epitaxy. Using the neutral and charged exciton emission as a monitor we observe the direct consequenc…
Controlling the polarization eigenstate of a quantum dot exciton with light
Thomas Belhadj, Claire-Marie Simon, Thierry Amand +6
We demonstrate optical control of the polarization eigenstates of a neutral quantum dot exciton without any external fields. By varying the excitation power of a circularly polariz…
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…
Efficient dynamical nuclear polarization in quantum dots: Temperature dependence
B. Urbaszek, P. -F. Braun, X. Marie +4
We investigate in micro-photoluminescence experiments the dynamical nuclear polarization in individual InGaAs quantum dots. Experiments carried out in an applied magnetic field of…
