Gigahertz-clocked Generation of Highly Indistinguishable Photons at C-band Wavelengths
Robert Behrends, Lucas Rickert, Nils D. Kewitz +9
High-performance single-photon sources at telecom C-band wavelentghs are key building blocks for applications in long-distance quantum communication. Here, we report the generation…
Electrically tunable orbital coupling and quantum light emission from O-band quantum dot molecules
P. S. Avdienko, L. Hanschke, Q. Buchinger +10
We present the observation of electrically tunable quantum coupling of orbital states in individual InAs/InGaAs quantum dot molecules emitting in the telecom O-band (~1300 nm). By…
Highly-Indistinguishable Single-Photons at 1550 nm from a Two-photon Resonantly Excited Purcell-enhanced Quantum Dot
Robert Behrends, Martin v. Helversen, Pratim K. Saha +10
In this work we present a cavity-enhanced InAs/ quantum dot (QD) single-photon source in the telecom C-band with a record-low biexciton emit…
Deterministic Quantum Dot Cavity Placement Using Hyperspectral Imaging with High Spatial Accuracy and Precision
Quirin Buchinger, Constantin Krause, Aileen Zhang +6
Single emitters in solid state are great sources of single and entangled photons. To boost their extraction efficiency and tailor their emission properties, they are often incorpor…
Purcell-Enhanced Single-Photon Emission in the Telecom C-Band
Jochen Kaupp, Yorick Reum, Felix Kohr +7
Purcell-enhanced quantum dot single-photon emission in the telecom C-band from InAs quantum dots inside circular Bragg grating cavities is shown. The InAs quantum dots are grown by…
Lingering Times at Resonance: The Case of Sb-based Tunneling Devices
Edgar David Guarin Castro, Andreas Pfenning, Fabian Hartmann +7
Concurrent natural time scales related to relaxation, recombination, trapping, and drifting processes rule the semiconductor heterostructures' response to external drives when char…
Optical mapping of non-equilibrium charge carriers
E. David Guarin Castro, A. Pfenning, F. Hartmann +6
We investigate the energy relaxation segmentation in a resonant tunneling heterostructures by assessing the optical and transport dynamics of non-equilibrium charge carriers. The e…
