Distance calibration via Newton's rings in yttrium lithium fluoride whispering gallery mode resonators
Josh T. Christensen, Farhan Azeem, Luke S. Trainor +2
In this work, we analyze the first whispering gallery mode resonator (WGMR) made from monocrystalline yttrium lithium fluoride (YLF). The disc-shaped resonator is fabricated using…
Ultra-low Threshold Titanium doped sapphire Whispering-gallery Laser
Farhan Azeem, Luke S. Trainor, Ang Gao +3
Titanium doped sapphire (Ti:sapphire) is a laser gain material with broad gain bandwidth benefiting from the material stability of sapphire. These favorable characteristics of Ti:s…
Nonlinear power dependence of the spectral properties of an optical parametric oscillator below threshold in the quantum regime
Golnoush Shafiee, Dmitry V. Strekalov, Alexander Otterpohl +6
Photon pairs and heralded single photons, obtained from cavity-assisted parametric down-conversion (PDC), play an important role in quantum communications and technology. This moti…
Polarization-selective out-coupling of whispering gallery modes
Florian Sedlmeir, Matthew R. Foreman, Ulrich Vogl +6
Whispering gallery mode (WGM) resonators are an important building block for linear, nonlinear and quantum optical experiments. In such experiments, independent control of coupling…
Nonlinear and Quantum Optics with Whispering Gallery Resonators
Dmitry V. Strekalov, Christoph Marquardt, Andrey B. Matsko +2
Optical Whispering Gallery Modes (WGMs) derive their name from a famous acoustic phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This phenomenon ha…
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…
