GHz bandwidth electro-optics of a single self-assembled quantum dot in a charge-tunable device
Jonathan H. Prechtel, Paul A. Dalgarno, Robert H. Hadfield +4
The response of a single InGaAs quantum dot, embedded in a miniaturized charge-tunable device, to an applied GHz bandwidth electrical pulse is investigated via its optical response…
Probing single charge fluctuations in a semiconductor with laser spectroscopy on a quantum dot
J. Houel, A. Kuhlmann, L. Greuter +10
We probe local charge fluctuations in a semiconductor via laser spectroscopy on a nearby self-assembled quantum dot. We demonstrate that the quantum dot is sensitive to changes in…
Laser spectroscopy of individual quantum dots charged with a single hole
B. D. Gerardot, R. J. Barbour, D. Brunner +6
We characterize the positively charged exciton (X1+) in single InGaAs quantum dots using resonant laser spectroscopy. Three samples with different dopant species (Be or C as accept…
Controlling the Interaction of Electron and Nuclear Spins in a Tunnel-Coupled Quantum Dot
C. Kloeffel, P. A. Dalgarno, B. Urbaszek +5
We present a technique for manipulating the nuclear spins and the emission polarization from a single optically active quantum dot. When the quantum dot is tunnel coupled to a Ferm…
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…
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…
