Photonic Wavepacket in Whispering-Gallery Modes
The Thirteenth International Conference on Ultrafast Phenomena, 2002We 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.

Dispersion compensation in whispering-gallery modes
Journal of the Optical Society of America A, 2003We 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 terahertz pulses
Optics Letters, 2002We 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.

Whispering gallery mode diamond resonator
Optics Letters, 2013We 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, 2012In 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.

Enhancing whispering gallery mode biosensing
2013 15th International Conference on Transparent Optical Networks (ICTON), 2013First, years of work on advancing the device physics and engineering of WGM biosensors has improved the ultimate physical detection limits of WGM transducers, yet the limits for DNA detection by hybridization has plateaued. Molecular recognition of DNA at a surface limits the biosensors' sensitivity, specificity, and reusability.

Surface whispering-gallery mode
EPL (Europhysics Letters), 2011Metamaterials can exhibit electromagnetic characteristics beyond those found in nature. In this letter, we demonstrate that Surface Whispering-gallery mode (SWGM) can be generated by coating a microresonator with a layer of metamaterials. Different from WGM, whose waves are mostly confined within the microresonator, the SWGM propagate at the interface ...

Classification of whispering gallery modes for cladded systems
Optics & Laser Technology, 2023International audience ; A classification of whispering gallery modes has been proposed between three types : core modes, cladding modes and composed modes. While core modes or cladding modes are interesting to generate with a sensor purpose, composed modes propagate in both core and coating and therefore should be avoided. In this paper, a theoretical
