Cascaded Raman lasing in a lithium tetraborate (LB4) whispering gallery mode resonator
Chengcai Tian, Florian Sedlmeir, Jervee Punzalan +5
Lithium tetraborate (LB4) is a lithium borate compound and recently has shown renewed interest due to its exceptional linear and nonlinear optical properties. Its wide transparency…
Dielectric tuning and coupling of whispering gallery modes using an anisotropic prism
Matthew R. Foreman, Florian Sedlmeir, Harald G. L. Schwefel +1
Optical whispering gallery mode (WGM) resonators are a powerful and versatile tool used in many branches of science. Fine tuning of the central frequency and line width of individu…
Near-infrared single-photon spectroscopy of a whispering gallery mode resonator using energy-resolving transition edge sensors
Michael Förtsch, Thomas Gerrits, Martin J. Stevens +9
We demonstrate a method to perform spectroscopy of near-infrared single photons without the need of dispersive elements. This method is based on a photon energy resolving transitio…
High-Q MgF whispering gallery mode resonators for refractometric sensing in aqueous environment
Florian Sedlmeir, Richard Zeltner, Gerd Leuchs +1
We present our experiments on refractometric sensing with ultrahigh-Q, crystalline, birefringent magnesium fluoride (MgF) whispering gallery mode resonators. The difference to…
Identifying modes of large whispering-gallery mode resonators from the spectrum and emission pattern
Gerhard Schunk, Josef U. Fürst, Michael Förtsch +6
Identifying the mode numbers in whispering-gallery mode resonators (WGMRs) is important for tailoring them to experimental needs. Here we report on a novel experimental mode analys…
Highly efficient generation of single-mode photon pairs using a crystalline whispering gallery mode resonator
Michael Förtsch, Gerhard Schunk, Josef U. Fürst +8
We report a highly efficient source of narrow-band photon pairs based on parametric down-conversion in a crystalline whispering gallery mode resonator. Remarkably, each photon of a…
