Coulomb mediated hybridization of excitons in artificial molecules
P. -L. Ardelt, K. Gawarecki, K. Müller +11
We report the Coulomb mediated hybridization of excitonic states in an optically active, artificial quantum dot molecule. By probing the optical response of the artificial molecule…
All optical quantum control of a spin-quantum state and ultrafast transduction into an electric current
K. Müller, T. Kaldewey, R. Ripszam +6
The ability to control and exploit quantum coherence and entanglement drives research across many fields ranging from ultra-cold quantum gases to spin systems in condensed matter.…
Broadband Purcell enhanced emission dynamics of quantum dots in linear photonic crystal waveguides
Arne Laucht, Thomas Günthner, Simon Pütz +8
The authors investigate the spontaneous emission dynamics of self-assembled InGaAs quantum dots embedded in GaAs photonic crystal waveguides. For an ensemble of dots coupled to gui…
High fidelity optical preparation and coherent Larmor precession of a single hole in an InGaAs quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy with photocurrent readout to directly probe the dynamics of a single hole spin in a single, electrically tunable self-assembled quantum…
A Waveguide-Coupled On-Chip Single Photon Source
A. Laucht, S. Pütz, T. Günthner +8
We investigate single photon generation from individual self-assembled InGaAs quantum dots coupled to the guided optical mode of a GaAs photonic crystal waveguide. By performing co…
Highly Non-linear Excitonic Zeeman Spin-Splitting in Composition-Engineered Artificial Atoms
V. Jovanov, T. Eissfeller, S. Kapfinger +8
Non-linear Zeeman splitting of neutral excitons is observed in composition engineered In(x)Ga(1-x)As self-assembled quantum dots and its microscopic origin is explained. Eight-band…
