Deterministic integration of quantum dots into on-chip multi-mode interference beamsplitters using in-situ electron beam lithography
Peter Schnauber, Johannes Schall, Samir Bounouar +8
The development of multi-node quantum optical circuits has attracted great attention in recent years. In particular, interfacing quantum-light sources, gates and detectors on a sin…
Micropillars with a controlled number of site-controlled quantum dots
Arsenty Kaganskiy, Fabian Gericke, Tobias Heuser +3
We report on the realization of micropillars with site-controlled quantum dots (SCQDs) in the active layer. The SCQDs are grown via the buried stressor approach which allows for th…
Enhancing the photon-extraction efficiency of site-controlled quantum dots by deterministically fabricated microlenses
Arsenty Kaganskiy, Sarah Fischbach, Andre Strittmatter +3
We report on the realization of scalable single-photon sources (SPSs) based on single site-controlled quantum dots (SCQDs) and deterministically fabricated microlenses. The fabrica…
Accessing the dark exciton spin in deterministic quantum-dot microlenses
Tobias Heindel, Alexander Thoma, Ido Schwartz +11
The dark exciton state in semiconductor quantum dots constitutes a long-lived solid-state qubit which has the potential to play an important role in implementations of solid-state…
Controlling the gain contribution of background emitters in few-quantum-dot microlasers
F. Gericke, M. Segnon, M. von Helversen +9
We provide experimental and theoretical insight into single-emitter lasing effects in a quantum dot (QD)-microlaser under controlled variation of background gain provided by off-re…
A stand-alone fiber-coupled single-photon source
Alexander Schlehahn, Sarah Fischbach, Ronny Schmidt +5
In this work, we present a stand-alone and fiber-coupled quantum-light source. The plug-and-play device is based on an optically driven quantum dot delivering single photons via an…
