Dressed excitonic states and quantum interference in a three-level quantum dot ladder system
B. D. Gerardot, D. Brunner, P. A. Dalgarno +4
We observe dressed states and quantum interference effects in a strongly driven three-level quantum dot ladder system. The effect of a strong coupling field on one dipole transitio…
Coulomb interactions in single, charged self-assembled quantum dots: radiative lifetime and recombination energy
P. A. Dalgarno, J. M. Smith, J. McFarlane +5
We present results on the charge dependence of the radiative recombination lifetime, Tau, and the emission energy of excitons confined to single self-assembled InGaAs quantum dots.…
Contrast in transmission spectroscopy of a single quantum dot
B. D. Gerardot, S. Seidl, P. A. Dalgarno +5
We perform transmission spectroscopy on single quantum dots and examine the effects of a resident carriers spin, the incident laser spot size, polarization, and power on the experi…
Manipulating exciton fine-structure in quantum dots with a lateral electric field
B. D. Gerardot, S. Seidl, P. A. Dalgarno +8
The fine structure of the neutral exciton in a single self assembled InGaAs quantum dot is investigated under the effect of a lateral electric field. Stark shifts up to 1.5 meV, an…
Power-law carrier dynamics in semiconductor nanocrystals at nanosecond time scales
P. H. Sher, J. M. Smith, P. A. Dalgarno +6
We report the observation of power law dynamics on nanosecond to microsecond time scales in the fluorescence decay from semiconductor nanocrystals, and draw a comparison between th…
Absorption and photoluminescence spectroscopy on a single self-assembled charge-tunable quantum dot
S. Seidl, M. Kroner, P. A. Dalgarno +8
We have performed detailed photoluminescence (PL) and absorption spectroscopy on the same single self-assembled quantum dot in a charge-tunable device. The transition from neutral…
