Quasi-polygonal Conformal Mappings for Designing Whispering Gallery Modes of Multiple Direction Emission [PDF]

open access: yesarXiv, 2019
We propose a series of conformal mappings for designing directional emission whispering gallery modes. The mappings transform circular cavity into quasi-polygonal transformation cavity. Anisotropic emission is demonstrated in the so-designed cavities.

Acoustic whispering-gallery modes in optomechanical shells

open access: yesNew Journal of Physics, 2012
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 ...

Chaotic light: a theory of asymmetric resonant cavities [PDF]

open access: yesOptical Processes in Microcavities, edited by R.K.Chang and A.J.Campillo (World Scientific Publishers, 1996), 2002
Spherical and cylindrical dielectric cavities support high Q whispering gallery modes due to total internal reflection of the trapped light. When such a cavity is deformed smoothly the ray dynamics of these modes becomes chaotic in a manner determined by the KAM theory of classical hamiltonian dynamics.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing

open access: yesSensing and Bio-Sensing Research, 2019
In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle
