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.…
Rapid spin depolarization in the layered 2D Ruddlesden Popper perovskite (BA)(MA)PbI
Michael Kempf, Philipp Moser, Maximilian Tomoscheit +8
We report temperature-dependent spectroscopy on the layered (n=4) two-dimensional (2D) Ruddlesden-Popper perovskite (BA)(MA)PbI. Helicity-resolved steady-state photoluminescence (P…
Probing Dark Excitons in Monolayer MoS by NonLinear Two-Photon Spectroscopy
Chenjiang Qian, Viviana Villafañe, Pedro Soubelet +3
We report a new dark exciton in monolayer MoS using second harmonic generation spectroscopy. Hereby, the spectrally dependent second harmonic generation intensity splits into t…
