Rack-integrated quantum dot-based source of single and entangled photons at telecom C-band
Michal Vyvlecka, Raphael Joos, Benjamin Breiholz +8
For quantum light sources in everyday telecommunication networks, quantum science needs to be fully transformed into quantum technology. The first necessary step to move outside a…
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…
High-Performance Labyrinth Circular Bragg Grating Design for Charge and Stark-Tunable Quantum Light Sources Spanning Visible to Telecom Wavelengths
Rohit Prasad, Quirin Buchinger, Fei Chi Kristy Yuen +3
Semiconductor quantum dots embedded in circular Bragg gratings (CBGs) are among the most efficient integrated single-photon sources. However, the fully etched rings of conventional…
Two-Photon Interference from an InAs Quantum Dot emitting in the Telecom C-Band
Jaewon Kim, Jochen Kaupp, Yorick Reum +9
Two-photon interference from an InAs/InAlGaAs quantum dot (QD) emitting in the telecom C-band with a raw two-photon interference visibility of % is demonstra…
