Measuring deviations from a perfectly circular cross-section of an optical nanofiber at the Ångström scale
Jihao Jia, Felix Tebbenjohanns, Thomas Hoinkes +3
Tapered optical fibers (TOFs) with sub-wavelength-diameter waists, known as optical nanofibers, are powerful tools for interfacing quantum emitters and nanophotonics. These applica…
Emergence of second-order coherence in superfluorescence
Constanze Bach, Felix Tebbenjohanns, Christian Liedl +2
We experimentally investigate the second-order quantum coherence function of a superradiant burst in a cascaded quantum system. We chirally (i.e. direction-dependently) couple roug…
Predicting correlations in superradiant emission from a cascaded quantum system
Felix Tebbenjohanns, Christopher D. Mink, Constanze Bach +2
In recent experiments, a novel type of cascaded quantum system has been realized using nanofiber-coupled cold atomic ensembles. This setup has enabled the study of superradiant dec…
Feedback-cooling the fundamental torsional mechanical mode of a tapered optical fiber to 30 mK
Felix Tebbenjohanns, Jihao Jia, Michael Antesberger +5
Tapered optical fibers (TOFs) are used in many areas of physics and optical technologies ranging from coupling light into nanophotonic components to optical sensing and amplificati…
Observation of superradiant bursts in a cascaded quantum system
Christian Liedl, Felix Tebbenjohanns, Constanze Bach +3
Dicke superradiance describes the collective radiative decay of a fully inverted ensemble of two-level atoms. We experimentally investigate this effect for a chiral, i.e.,~directio…
Encoding information in the mutual coherence of spatially separated light beams
Alfonso Nardi, Shawn Divitt, Massimiliano Rossi +4
Coherence has been used as a resource for optical communications since its earliest days. It is widely used for multiplexing of data, but not for encoding of data. Here we introduc…
