Review of Applications of Whispering-Gallery Mode Resonators in Photonics and Nonlinear Optics
نویسندگان
چکیده
We review recent advances in the application of dielectric whispering-gallery (WG) resonators in optics and photonics, tracing the growth of the technology from the experiments with freely flying spherical droplets of transparent liquids to integrated on-chip microresonators. Both passive (such as filters) and active (such as lasers) whispering-gallery-mode (WGM)-based devices are discussed. Problems and possible future developments in the field are outlined.

Nonlinear Optics and Crystalline Whispering Gallery Mode resonators
We report on our recent results concerning fabrication of high-Q whispering gallery mode (WGM) crystalline resonators, and discuss some possible applications of lithium niobate WGM resonators in nonlinear optics and photonics. In particular, we demonstrate experimentally a tunable third-order optical filter fabricated from the three metalized resonators; and report observation of parametric fre...
متن کاملBarium fluoride whispering-gallery-mode disk-resonator with one billion quality-factor.
We demonstrate a monolithic optical whispering-gallery-mode resonator fabricated with barium fluoride (BaF₂) with an ultra-high quality (Q) factor above 10⁹ at 1550 nm, and measured with both the linewidth and cavity-ring-down methods. Vertical scanning optical profilometry shows that the root mean square surface roughness of 2 nm is achieved for our mm-size disk. To the best of our knowledge, ...
متن کاملInterfacing whispering-gallery microresonators and free space light with cavity enhanced Rayleigh scattering
Whispering gallery mode resonators (WGMRs) take advantage of strong light confinement and long photon lifetime for applications in sensing, optomechanics, microlasers and quantum optics. However, their rotational symmetry and low radiation loss impede energy exchange between WGMs and the surrounding. As a result, free-space coupling of light into and from WGMRs is very challenging. In previous ...

متن کاملIdentifying modes of large whispering-gallery mode resonators from the spectrum and emission pattern.
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 analysis technique based on the combination of frequency analysis and far-field imaging for high mode numbers of large WGMRs. The radial mode numbers q and the angular mode numbers p = ℓ-m are identified and labeled via far...
