Polarization properties of excitonic qu-bits in single self-assembled quantum dots
C. Tonin, R. Hostein, V. Voliotis +3
We investigate polarization properties of neutral exciton emission in single self-assembled InAs/GaAs quantum dots. The in-plane shape and strain anisotropy strongly couple the hea…
Polariton condensation in photonic molecules
Marta Galbiati, Lydie Ferrier, Dmitry D. Solnyshkov +9
We report on polariton condensation in photonic molecules formed by two coupled micropillars. We show that the condensation process is strongly affected by the interaction with the…
Optical pumping and non-destructive readout of a single magnetic impurity spin in an InAs/GaAs quantum dot
Emmanuel Baudin, Emile Benjamin, Aristide Lemaître +1
We report on the resonant optical pumping of the |\pm1> spin states of a single Mn dopant in an InAs/GaAs quantum dot embedded itself in a charge tuneable device. The experiment re…
Isotope sensitive measurement of the hole-nuclear spin interaction in quantum dots
E. A. Chekhovich, A. B. Krysa, M. Hopkinson +4
Decoherence caused by nuclear field fluctuations is a fundamental obstacle to the realization of quantum information processing using single electron spins. Alternative proposals h…
Ultra-low threshold polariton lasing in photonic crystal cavities
Stefano Azzini, Dario Gerace, Matteo Galli +5
The authors show clear experimental evidence of lasing of exciton polaritons confined in L3 photonic crystal cavities. The samples are based on an InP membrane in air containing fi…
Full control of spontaneous emission in confined Tamm plasmon structures
O. Gazzano, S. Michaelis de Vasconcellos, K. Gauthron +6
We demonstrate strong confinement of the optical field by depositing a micron sized metallic disk on a planar interferential mirror. Zero dimensional Tamm plasmon modes are evidenc…
