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…
Transverse-mode coupling effects in scanning cavity microscopy
Julia Benedikter, Thea Moosmayer, Matthias Mader +2
Tunable open-access Fabry-Pérot microcavities enable the combination of cavity enhancement with high resolution imaging. To assess the limits of this technique originating from bac…
A Diamond-Photonics Platform Based on Silicon-Vacancy Centers in a Single Crystal Diamond Membrane and a Fiber-Cavity
Stefan Häußler, Julia Benedikter, Kerem Bray +6
We realize a potential platform for an efficient spin-photon interface, namely negatively-charged silicon-vacancy centers in a diamond membrane coupled to the mode of a fully-tunab…
Cavity-enhanced spectroscopy of a few-ion ensemble in Eu3+:Y2O3
Bernardo Casabone, Julia Benedikter, Thomas Hümmer +7
We report on the coupling of the emission from a single europium-doped nanocrystal to a fiber-based microcavity under cryogenic conditions. As a first step, we study the sample pro…
