H1 photonic crystal cavitites for hybrid quantum information protocols
Jenna Hagemeier, Cristian Bonato, Tuan-Anh Truong +7
Hybrid quantum information protocols are based on local qubits, such as trapped atoms, NV centers, and quantum dots, coupled to photons. The coupling is achieved through optical ca…
Influence of the charge carrier tunneling processes on the recombination dynamics in single lateral quantum dot molecules
C. Hermannstädter, G. J. Beirne, M. Witzany +7
We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunnelin…
InP-quantum dots in Al0.20Ga0.80InP with different barrier configurations
Wolfgang-Michael Schulz, Robert Rossbach, Matthias Reischle +3
Systematic ensemble photoluminescence studies have been performed on type-I InP-quantum dots in Al0.20Ga0.80InP barriers, emitting at approximately 1.85 eV at 5 K. The influence of…
Exciton Dynamics on Rubrene (001) Crystal Surfaces with Microstructure Confinement
R. J. Stoehr, G. J. Beirne, P. Michler +3
The exciton dynamics on flat (001) rubrene crystal surfaces have been compared with those under confined pyramidal geometry by time-resolved photoluminescence with micrometer spati…
Polarization fine-structure and enhanced single-photon emission of self-assembled lateral InGaAs quantum dot molecules embedded in a planar micro-cavity
C. Hermannstädter, M. Witzany, G. J. Beirne +8
Single lateral InGaAs quantum dot molecules have been embedded in a planar micro-cavity in order to increase the luminescence extraction efficiency. Using a combination of metal-or…
