Optical Charge Injection and Full Coherent Control of Spin-Qubit in the Telecom C-band Emitting Quantum Dot
Łukasz Dusanowski, Cornelius Nawrath, Simone L. Portalupi +5
Solid-state quantum emitters with manipulable spin-qubits are promising platforms for quantum communication applications. Although such light-matter interfaces could be realized in…
Quantum interference between independent solid-state single-photon sources separated by 300 km fiber
Xiang You, Ming-Yang Zheng, Si Chen +23
In the quest to realize a scalable quantum network, semiconductor quantum dots (QDs) offer distinct advantages including high single-photon efficiency and indistinguishability, hig…
Excited states of neutral and charged excitons in single strongly asymmetric InP-based nanostructures emitting in the telecom C band
M. Gawełczyk, P. Wyborski, P. Podemski +3
We investigate strongly asymmetric self-assembled nanostructures with one of dimensions reaching hundreds of nanometers. Close to the nanowire-like type of confinement, such object…
Effects of the linear polarization of polariton condensates in their propagation in codirectional couplers
Elena Rozas, Alexey Yulin, Johannes Beierlein +9
We report on the linear polarization of polariton condensates in a codirectional coupler that allows evanescent coupling between adjacent waveguides. We observe polarization-depend…
Intrinsic circularly-polarized exciton emission in a twisted van-der-Waals heterostructure
J. Michl, S. A. Tarasenko, F. Lohof +12
The investigation of excitons in van-der-Waals heterostructures has led to profound insights into the interplay of crystal symmetries and fundamental effects of light-matter coupli…
Spatial coherence of room-temperature monolayer WSe exciton-polaritons in a trap
Hangyong Shan, Lukas Lackner, Bo Han +16
The emergence of spatial and temporal coherence of light emitted from solid-state systems is a fundamental phenomenon, rooting in a plethora of microscopic processes. It is intrins…
Quantifying quantum coherence in polariton condensates
Carolin Lüders, Matthias Pukrop, Elena Rozas +5
We theoretically and experimentally investigate quantum features of an interacting light-matter system from a multidisciplinary perspective, unifying approaches from semiconductor…
Purcell-enhanced single photon source based on a deterministically placed WSe monolayer quantum dot in a circular Bragg grating cavity
O. Iff, Q. Buchinger, M. Moczała-Dusanowska +6
We demonstrate a deterministic Purcell-enhanced single-photon source realized by integrating an atomically thin WSe layer with a circular Bragg grating cavity. The cavity sig…
Fiber-pigtailing quantum-dot cavity-enhanced light emitting diodes
Lucas Rickert, Frederik Schröder, Timm Gao +3
We report on a process for the fiber-coupling of electrically driven cavity-enhanced quantum dot light emitting devices. The developed technique allows for the direct and permanent…
Difference-frequency generation in an AlGaAs Bragg-reflection waveguide using an on-chip electrically-pumped quantum dot laser
A. Schlager, M. Götsch, R. J. Chapman +7
Nonlinear frequency conversion is ubiquitous in laser engineering and quantum information technology. A long-standing goal in photonics is to integrate on-chip semiconductor laser…
