Three‐wave mixing in whispering gallery resonators
Laser & Photonics Reviews, 2016AbstractWe review the progress in the development of frequency converters based on three‐wave mixing in whispering gallery resonators (WGRs). The theoretical description, given in a unified notation for all basic processes, reveals that the phase‐matching condition known from conventional devices is replaced by several selection rules and, furthermore,

Whispering gallery waves localized near circular isobaths in shallow water
The Journal of the Acoustical Society of America, 2019Sound propagation in an area of shallow sea with circular isobaths and the bottom depth increasing towards their curvature center is considered. Such an area could be part of a bay, a lagoon, or a lake with bowl-like bottom relief. The possible formation of whispering gallery waves localized in the vicinity of curved isobaths is considered.

Optical solitons appearing during propagation of whispering-gallery waves
Quantum Electronics, 2003The properties of solitons appearing during the propagation of whispering-gallery waves in a homogeneous glass cylinder are considered. It is shown that such solitons can be used for the light frequency conversion.

Whispering gallery modes in rutile resonators at millimeter wave frequencies
13th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2000. Conference Proceedings (IEEE Cat. No.00EX428), 2002Whispering gallery modes in single crystal rutile resonator were measured at the frequency range 15-30 GHz. Predicted and measured values of resonant frequencies for several WGM were in excellent agreement. Permittivity components parallel and perpendicular to anisotropy axis have been evaluated and their values were /spl epsi//sub /spl perp//=85.8/spl

Wave Front Sets of the Buldyrev Head Wave and Whispering Gallery Waves
Journal of Mathematical Sciences, 2016The diffraction of waves, produced by a point source, on an inhomogeneous half-plane is considered. The square of the wave number inside an inhomogeneous region is assumed to decrease linearly with the distance from the division boundary. Using the results obtained earlier, the Buldyrev head wave and whispering gallery waves are analyzed.

Acoustic whispering gallery mode coupling with Lamb waves in liquid
Sensors and Actuators A: Physical, 2013Acoustic whispering gallery modes (WGMs) in a micro-quartz tube immersed in liquid medium, excited by the evanescent wave of a Lamb wave device, are demonstrated. These excited WGMs exhibit characteristics similar to those of optical WGMs, such as narrow periodic transmission dips and a high quality factor.

Evanescent wave coupling of whispering gallery modes of a dielectric cylinder
IEE Proceedings J Optoelectronics, 1993By developing a direct correspondence between a given whispering gallery mode of a dielectric cylinder and a mode of an equivalent waveguide ring resonator, the evanescent wave coupling characteristics of such modes can be simply modelled. This also allows the conditions for resonant excitation of a single whispering gallery mode to be determined.

High-Q whispering gallery travelling wave resonators for oscillator frequency stabilisation
Proceedings of the 1999 Joint Meeting of the European Frequency and Time Forum and the IEEE International Frequency Control Symposium (Cat. No.99CH36313), 2000Usually a frequency-stabilized standing wave resonator-oscillator incorporating a resonator as a frequency discriminator requires a circulator to separate the injected and reflected wave, A ferrite circulator is a noisy device and can limit the phase noise or frequency stability. Moreover, we show that the noise in a circulator varies, and detailed low

Excitation coefficients of whispering gallery waves in a neighborhood of a flat point of a concave boundary [PDF]
Journal of Soviet Mathematics, 1982 A method is proposed for the computer calculation of the excitation coefficients of whispering gallery waves which arise beyond a flat point of a concave boundary when a single whispering gallery wave is incident on this point. Values of the moduli of these coefficients are presented for the incidence of the first and second whispering gallery waves ...
