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…
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…
Experimental characterization of an uniaxial angle cut whispering gallery mode resonator
Florian Sedlmeir, Martin Hauer, Josef U. Fürst +2
The usual configuration of uniaxial whispering gallery mode resonators is a disk shaped geometry where the optic axis points along the symmetry axis, a so called z-cut resonator. R…
A Versatile Source of Single Photons for Quantum Information Processing
Michael Förtsch, Josef Fürst, Christoffer Wittmann +6
The quantum state of a single photon stands among the most fundamental and intriguing manifestations of quantum physics. At the same time single photons and pairs of single photons…
Low-threshold Optical Parametric Oscillations in a Whispering Gallery Mode Resonator
J. U. Fürst, D. V. Strekalov, D. Elser +4
In whispering gallery mode (WGM) resonators light is guided by continuous total internal reflection along a curved surface. Fabricating such resonators from an optically nonlinear…
Quantum Light from a Whispering Gallery Mode Disk Resonator
J. U. Fürst, D. V. Strekalov, D. Elser +4
Optical parametric downconversion has proven to be a valuable source of nonclassical light. The process is inherently able to produce twin beam correlations along with individual i…
