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 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.

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 ...

Whispering Gallery Mode Devices
2020Whispering gallery mode (WGM) resonators and lately photonic crystal resonator based devices are attractive due to their potential applications in photonics and recently in biophotonics as is described in the previous chapter. Applications which have been realized include for example lasers, filters, optical switches and biosensors.

Nonlinear Whispering Gallery Modes
Physical Review Letters, 1999The stationary lasing of the modes in a microdisk is formulated as a nonlinear eigenvalue problem for a nonlinear Maxwell equation. It is shown that whispering gallery modes can be obtained as stationary lasing solutions with finite pumping thresholds.

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.

Polymeric whispering gallery mode micro-resonators
2016 IEEE Photonics Conference (IPC), 2016We review fabrication and optics of polymeric high-Q whispering gallery mode resonators. They are employed as bio-sensors featuring selective parallel functionalization of arrays and integration into lab-on-a-chip systems. Liquid crystalline elastomers enable wide tunability of resonances.

Whispering Gallery Modes Microcavity
2021This chapter introduces the origin of the Whispering-gallery modes (WGM) microcavities. The WGM microcavities have independent optical and mechanical properties. Several terminologies, such as optical or mechanical quality factor, used in cavities are introduced. The mode characterization and field distribution of the microsphere is discussed.

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.
