Fast optoelectronic charge state conversion of silicon vacancies in diamond
Manuel Rieger, Viviana Villafane, Lina M. Todenhagen +5
Group IV vacancy color centers in diamond are promising spin-photon interfaces with strong potential for applications for photonic quantum technologies. Reliable methods for contro…
Transfer Matrix Model for Emission Profile Optimization of Radial Gratings
Stefan Appel, Viviana Villafane, Jonathan J. Finley +1
Radial Bragg gratings are commonly used to enhance light extraction from quantum emitters, but lack a well-suited, fast simulation method for optimization beyond periodic designs.…
Signatures of dynamically dressed states
Katarina Boos, Sang Kyu Kim, Thomas Bracht +10
The interaction of a resonant light field with a quantum two-level system is of key interest both for fundamental quantum optics and quantum technological applications employing re…
Site-Selective Enhancement of Superconducting Nanowire Single-Photon Detectors via Local Helium Ion Irradiation
Stefan Strohauer, Fabian Wietschorke, Lucio Zugliani +9
Achieving homogeneous performance metrics between nominally identical pixels is challenging for the operation of arrays of superconducting nanowire single-photon detectors (SNSPDs)…
Nonlinear Dispersion Relation and Out-of-Plane Second Harmonic Generation in MoSSe and WSSe Janus Monolayers
Marko M. Petrić, Viviana Villafañe, Paul Herrmann +9
Janus transition metal dichalcogenides are an emerging class of atomically thin materials with engineered broken mirror symmetry that gives rise to long-lived dipolar excitons, Ras…
Heterogeneous integration of superconducting thin films and epitaxial semiconductor heterostructures with Lithium Niobate
Michelle Lienhart, Michael Choquer, Emeline D. S. Nysten +5
We report on scalable heterointegration of superconducting electrodes and epitaxial semiconductor quantum dots on strong piezoelectric and optically nonlinear lithium niobate. The…
