High-Q TM whispering-gallery modes in three-dimensional microcylinders

, 2007
We present a generation condition for realizing high-Q TM whispering-gallery modes (WGMs) in semiconductor microcylinders. For microcylinders with symmetry or weak asymmetry vertical waveguiding, we show that TM WGMs can have a high Q factor, with the ...

Folded chaotic whispering-gallery modes in non-convex, waveguide-coupled planar optical microresonators

, 2019
Chaotic whispering-gallery modes have significance both for optical applications and for our understanding of the interplay between wave phenomena and the classical ray limit in the presence of chaotic dynamics and openness.

DNA Sensing with Whispering Gallery Mode Microlasers

Nano Letters
Nucleic acid sensing is crucial for advancing diagnostics, therapeutic monitoring and molecu-lar biology research, by enabling the precise identification of DNA and RNA interactions. Here, we present an innovative sensing platform based on DNA-functionalized whispering gallery mode (WGM) microlasers.

Q-factor and waveguide-sphere separation effects in waveguide-coupled microsphere resonators

Quality-factors of waveguide coupled microsphere resonators of 30µm diameter are measured. A Teflon buffer layer is deposited on the waveguide to separate the microsphere from the waveguide and the effect of this separation on the measured quality-factor

Theory of resonance shifts of whispering gallery modes by arbitrary plasmonic nanoparticles

, 2013
Shifts of the resonance frequency of high Q whispering gallery modes (WGMs) in spherical dielectric microresonators by plasmonic nanoparticles can be greater than the WGM line width, such that the perturbation theory commonly used for describing ...
