Optomechanics with Surface-Acoustic-Wave Whispering-Gallery Modes [PDF]
Physical Review Letters, 2009 A surface acoustic wave (SAW) creates its own high-Q ultra-small volume whispering gallery modes (WGMs), different from usual bulk acoustic WGMs, in an optical dielectric WGM resonator. We show that it is possible to realize an externally controllable, efficient triply-resonant opto-mechanical interaction between two optical WGMs and the SAW WGM and to

Photonic lenses with whispering gallery waves at Janus particles
Opto-Electronic Science, 2022 We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder. These resonances are related to the excited whispering gallery waves caused by truncation. It is a new mechanism of the field localization.

Surface Waves of Rayleigh and Whispering Gallery Type [PDF]
The Journal of the Acoustical Society of America, 1973 Surface waves on smooth curved boundaries consist of an infinite number of modes, the lowest of which may be classified as of “Rayleigh type,” since it tends towards the Rayleigh wave in the limit of vanishing curvature. The others, which correspond to the “Whispering Gallery” modes of Lord Rayleigh, combine to form the lateral wave(s) in the zero ...

Optical rogue waves in whispering-gallery-mode resonators [PDF]
Physical Review A, 2014 We report a theoretical study showing that rogue waves can emerge in whispering gallery mode resonators as the result of the chaotic interplay between Kerr nonlinearity and anomalous group-velocity dispersion. The nonlinear dynamics of the propagation of light in a whispering gallery-mode resonator is investigated using the Lugiato-Lefever equation ...

Particle acceleration by wave scattering off dielectric spheres at whispering-gallery-mode resonance [PDF]
Physical Review Special Topics. Accelerators and Beams, 2007 The large electromagnetic fields, created in wave scattering near a perfect dielectric sphere at the condition of whispering-gallery-mode resonances, are investigated as driving units for high energy charged particle accelerators.

Far-field phonon coupling in valley metamaterial circuits [PDF]
Nature CommunicationsOn-chip whispering-gallery-mode cavities enable versatile bosonic wave manipulation but typically rely on near-field evanescent coupling. Here we experimentally demonstrate broadband far-field phonon coupling in a valley metamaterial cavity integrated ...

Continuous-wave whispering-gallery optical parametric oscillator based on CdSiP2
Optics Express, 2018 Continuous-wave (cw) optical parametric oscillators (OPOs) are ideally suited for applications, for example high-resolution spectroscopy, that need coherent sources combining narrow-linewidth emission with good wavelength tunability. Here, we demonstrate for the first time cw OPOs based on a millimeter-sized whispering gallery resonator (WGR) made of ...

ANALYSIS OF X-RAY WHISPERING GALLERY WAVES PROPAGATING ALONG LIQUID MENISCUSES
Resource-Efficient Technologies, 2018 X-ray diffraction and fluorescence of whispering galleries (WGs) which propagate along meniscuses of deionized water or silica hydrosols enriched by CsOH have been analyzed for the first time. The measurements have been performed using the diffractometer with a moving tube-detector system.
