We review our recent work on tunable, ultra-high quality factor whispering-gallery-mode bottle microresonators and highlight their applications in non-linear optics and in quantum optics experiments. Our resonators combine ultra-high quality factors of up to Q=3.6×108, a small mode volume, and near-lossless fiber coupling, with a simple and customizable mode structure enabling full tunability. We...
The paper here presents a fully tunable ultra-high-Q-whispering-gallery-mode "bottle microresonator", fabricated from standard optical glass fibres. Due to its highly prolate shape, the bottle microresonator gives rise to a class of whispering-gallery-modes (WGMs) with advantageous properties. In addition to the radial confinement by continuous total internal reflection at the resonator...
Whispering-gallery-mode (WGM) resonators, i.e., monolithic structures in which light is confined by continuous total internal reflection, offer a row of desirable properties. They realize the highest Q values for optical resonators to date. In addition, their relatively small mode volume of V ~1000??3, where ?? is the optical wavelength, allows to reach a high intra-cavity intensity for a small total...
