Photonic Wavepacket in Whispering-Gallery Modes

The Thirteenth International Conference on Ultrafast Phenomena, 2002
We have generated a wavepacket in optical whispering-gallery modes of a dielectric sphere and observed its round trip motion along the periphery. The data is compared with the calculation based on a Mie scattering theory.

Whispering-gallery mode terahertz pulses

Optics Letters, 2002
We report what is to our knowledge the first observation of a subpicosecond terahertz (THz) pulse propagating as a superposition of the whispering-gallery modes (WGMs) of a dielectric cylinder. The WGM THz pulses are coupled into and out of a 5-mm-diameter silicon cylinder via a 100-mum -thick, single-mode silicon slab waveguide.

Dispersion compensation in whispering-gallery modes

Journal of the Optical Society of America A, 2003
We show that manipulation by a spatial profile of the refractive index of a circularly symmetric dielectric cavity results in a novel way of fine tuning frequency separations as well as spatial localizations of high-Q whispering-gallery modes excited in the cavity.

Whispering gallery mode diamond resonator

Optics Letters, 2013
We demonstrate a nearly spherical diamond whispering gallery mode resonator with quality factor (Q factor) Q=2.4×10(7) limited by material loss approaching α=4×10(-3) cm(-1). The Q factor does not depend on the wavelength: it is approximately the same at 1319 and 1550 nm. Resonators with this range of Q (

Whispering Gallery Mode Microresonators for Biosensing

Advances in Science and Technology, 2012
In the field of sensing, WGM microresonators are receiving a growing interest as optical structures suitable for the realization of miniature sensors with high sensitivity. When properly excited, WGM microresonators are able to strongly confine light, by means of total internal reflection,along the equatorial plane near their spherical surface.
