Characterization of harmonic modes and parasitic resonances in multi-mode superconducting coplanar resonators
Cenk Beydeda, Konstantin Nikolaou, Marius Tochtermann +8
Planar superconducting microwave transmission line resonators can be operated at multiple harmonic resonance frequencies. This allows covering wide spectral regimes with high sensi…
Laser written mirror profiles for open-access fiber Fabry-Pérot microcavities
Jannis Hessenauer, Ksenia Weber, Julia Benedikter +4
We demonstrate laser-written concave hemispherical structures produced on the endfacets of optical fibers that serve as mirror substrates for tunable open-access microcavities. We…
Phase-locked photon-electron interaction without a laser
Masoud Taleb, Mario Hentschel, Kai Rossnagel +2
Ultrafast electron-photon spectroscopy in electron microscopes commonly requires ultrafast laser setups. Photoemission from an engineered electron source is used to generate pulsed…
Microscopic 3D printed optical tweezers for atomic quantum technology
Pavel Ruchka, Sina Hammer, Marian Rockenhäuser +5
Trapping of single ultracold atoms is an important tool for applications ranging from quantum computation and communication to sensing. However, most experimental setups, while ver…
Dielectric Mie Voids: Confining Light in Air
Mario Hentschel, Kirill Koshelev, Florian Sterl +6
Manipulating light on the nanoscale has become a central challenge in metadevices, resonant surfaces, nanoscale optical sensors, and many more, and it is largely based on resonant…
Numerical optimization of single-mode fiber-coupled single-photon sources based on semiconductor quantum dots
Lucas Bremer, Carlos Jimenez, Simon Thiele +8
We perform extended numerical studies to maximize the overall photon coupling efficiency of fiber-coupled quantum dot single-photon sources emitting in the near-infrared and teleco…
