Permanent tuning of quantum dot transitions to degenerate microcavity resonances
Jan Gudat, Cristian Bonato, Evert van Nieuwenburg +5
We demonstrate a technique for achieving spectral resonance between a polarization-degenerate micropillar cavity mode and an embedded quantum dot transition. Our approach is based…
Strong coupling between quantum dot exciton spin states and a photonic crystal cavity
Hyochul Kim, Thomas C. Shen, Deepak Sridharan +2
We apply magnetic fields of up to 7 T to an indium arsenide (InAs) quantum dot (QD) strongly coupled to a photonic crystal cavity. The field lifts the degeneracy of QD exciton spin…
Recent progress towards acoustically mediated carrier injection into individual nanostructures for single photon generation
Stefan Völk, Florian J. R. Schülein, Florian Knall +12
We report on recent progress towards single photon sources based on quantum dot and quantum post nanostructures which are manipulated using surface acoustic waves. For this concept…
Enhanced sequential carrier capture into individual quantum dots and quantum posts controlled by surface acoustic waves
Stefan Völk, Florian J. R. Schülein, Florian Knall +7
Individual self-assembled Quantum Dots and Quantum Posts are studied under the influence of a surface acoustic wave. In optical experiments we observe an acoustically induced switc…
Ultrafast Optical Response of a High-Reflectivity GaAs/AlAs Bragg Mirror
Sara R. Hastings, Michiel J. A. de Dood, Hyochul Kim +3
The ultrafast response of a high-reflectivity GaAs/AlAs Bragg mirror to optical pumping is investigated for all-optical switching applications. Both Kerr and free carrier nonlinear…
