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 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.

Surface whispering-gallery mode

EPL (Europhysics Letters), 2011
Metamaterials 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

2020
Whispering 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, 1999
The 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.
