Whispering gallery modes
Whispering gallery modes are specific resonances (or modes) of a wave field that are confined inside a given resonator (cavity) with smooth edges due to continuous total internal reflection. The most interesting from a practical viewpoint are electromagnetic whispering gallery modes, since they posses many unique properties, such as ultra-high Q-factors, low mode volumes, small sizes of resonat...
متن کاملAcoustic whispering-gallery modes in optomechanical shells
We numerically calculate the forms and frequencies of mechanical whispering-gallery modes in silica shells. Such modes were recently experimentally observed in water-filled optomechanical resonators, which constitute a bridge between optomechanics and microfluidics. We consider the three acoustic mode families of Rayleigh–Lamb waves, longitudinal waves and Love waves. Our study shows that these...
متن کاملMicrotorus: a high-finesse microcavity with whispering-gallery modes.
We demonstrate a 165-mu;m oblate spheroidal microcavity with a free spectral range of 383.7 GHz (3.06 nm), a resonance bandwidth of 23 MHz (quality factor Q approximately 10(7)) at 1550 nm, and finesse F>/=10(4) . The highly oblate spheroidal dielectric microcavity combines a very high Q factor, typical of microspheres, with a vastly reduced number of excited whispering-gallery modes (by 2 orde...
متن کاملWhispering gallery modes inside asymmetric resonant cavities.
Two dimensional resonators with a smooth strictly convex boundary are known to possess a whispering gallery region supporting modes concentrated near the boundary. A new class of asymmetric resonant cavities is introduced, where a whispering gallery-like region is found deep inside the resonator. The construction of such resonators is a novel application of the geometric control methods. The re...

Watson Laboratories of Applied Physics California Institute of Technology Pasadena, CA 91125, USA E-mail: [email protected] For thin-fi lm solar cells, light absorption is usually proportional to the fi lm thickness. However, if freely propagating sunlight can be transformed into...
