Coexistence of weak and strong coupling with a quantum dot in a photonic molecule
S. Lichtmannecker, M. Kaniber, S. Echeverri-Arteaga +12
We study the emission from a molecular photonic cavity formed by two proximal photonic crystal defect cavities containing a small number (<3) of In(Ga)As quantum dots. Under strong…
Integrated superconducting detectors on semiconductors for quantum optics applications
Michael Kaniber, Fabian Flassig, Günther Reithmaier +2
Semiconductor quantum photonic circuits can be used to efficiently generate, manipulate, route and exploit non-classical states of light for distributed photon based quantum inform…
On-chip generation, routing and detection of quantum light
Günther Reithmaier, Michael Kaniber, Fabian Flassig +6
Semiconductor based photonic information technologies are rapidly being pushed to the quantum limit where non-classical states of light can be generated, manipulated and exploited…
A carrier relaxation bottleneck probed in single InGaAs quantum dots using integrated superconducting single photon detectors
G. Reithmaier, F. Flassig, P. Hasch +6
Using integrated superconducting single photon detectors we probe ultra-slow exciton capture and relaxation dynamics in single self-assembled InGaAs quantum dots embedded in a GaAs…
Highly directed emission from self-assembled quantum dots into guided modes in disordered photonic crystal waveguides
Thorsten Reichert, Stefan Lichtmannecker, Günther Reithmaier +7
We explore the dynamics and directionality of spontaneous emission from self-assembled In(Ga)As quantum dots into TE-polarised guided modes in GaAs two-dimensional photonic crystal…
On-chip time resolved detection of quantum dot emission using integrated superconducting single photon detectors
Günther Reithmaier, Stefan Lichtmannecker, Thorsten Reichert +5
We report the routing of quantum light emitted by self-assembled InGaAs quantum dots (QDs) into the optical modes of a GaAs ridge waveguide and its efficient detection on-chip via…
Optimisation of NbN thin films on GaAs substrates for in-situ single photon detection in structured photonic devices
Günther Reithmaier, Jörg Senf, Stefan Lichtmannecker +5
We prepare NbN thin films by DC magnetron sputtering on [100] GaAs substrates, optimise their quality and demonstrate their use for efficient single photon detection in the near-in…
Electrical control of inter-dot electron tunneling in a quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy to directly monitor electron tunneling between discrete orbital states in a pair of spatially separated quantum dots. Immediately after…
Excited State Quantum Couplings and Optical Switching of an Artificial Molecule
K. Müller, G. Reithmaier, E. C. Clark +6
We optically probe the spectrum of ground and excited state transitions of an individual, electrically tunable self-assembled quantum dot molecule. Photocurrent absorption measurem…
