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…
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…
Absorptive and dispersive optical responses of excitons in a single quantum dot
B. Alén, A. Högele, M. Kroner +6
We have determined both the real and imaginary parts of the dielectric polarizability of a single quantum dot. The experiment is based on the observation and the manipulation of Ra…
Spin-selective optical absorption of singly charged excitons in a quantum dot
A. Högele, M. Kroner, S. Seidl +8
We investigate high resolution laser absorption spectroscopy of a single InGaAs/GaAs self-assembled quantum dot embedded in a field-effect structure. We show experimentally that th…
Voltage-Controlled Optics of a Quantum Dot
A. Högele, S. Seidl, M. Kroner +4
We show how the optical properties of a single semiconductor quantum dot can be controlled with a small dc voltage applied to a gate electrode. We find that the transmission spectr…
