High resolution coherent population trapping on a single hole spin in a semiconductor
Julien Houel, Jonathan H. Prechtel, Daniel Brunner +5
We report high resolution coherent population trapping on a single hole spin in a semiconductor quantum dot. The absorption dip signifying the formation of a dark state exhibits an…
Electro-elastic tuning of single particles in individual self-assembled quantum dots
Chris E. Kuklewicz, Ralph N. E. Malein, Pierre M. Petroff +1
We investigate the effect of uniaxial stress on InGaAs quantum dots in a charge tunable device. Using Coulomb blockade and photoluminescence, we observe that significant tuning of…
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…
