Narrow optical linewidths and spin pumping on charge-tunable, close-to-surface self-assembled quantum dots in an ultra-thin diode
Matthias C. Löbl, Immo Söllner, Alisa Javadi +9
We demonstrate full charge control, narrow optical linewidths, and optical spin pumping on single self-assembled InGaAs quantum dots embedded in a thin diode str…
Optical nanoscopy via quantum control
Timo Kaldewey, Andreas V. Kuhlmann, Sascha R. Valentin +3
We present a scheme for nanoscopic imaging of a quantum mechanical two-level system using an optical probe in the far-field. Existing super-resolution schemes require more than two…
Indistinguishable and efficient single photons from a quantum dot in a planar nanobeam waveguide
Gabija Kiršanskė, Henri Thyrrestrup, Raphaël S. Daveau +16
We demonstrate a high-purity source of indistinguishable single photons using a quantum dot embedded in a nanophotonic waveguide. The source features a near-unity internal coupling…
Coherent and robust high-fidelity generation of a biexciton in a quantum dot by rapid adiabatic passage
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +6
A biexciton in a semiconductor quantum dot is a source of polarization-entangled photons with high potential for implementation in scalable systems. Several approaches for non-reso…
Demonstrating the decoupling regime of the electron-phonon interaction in a quantum dot using chirped optical excitation
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +7
Excitation of a semiconductor quantum dot with a chirped laser pulse allows excitons to be created by rapid adiabatic passage. In quantum dots this process can be greatly hindered…
