Polarization-selective out-coupling of whispering gallery modes [PDF]
, 2016 Whispering gallery mode (WGM) resonators are an important building block for linear, nonlinear and quantum optical experiments. In such experiments, independent control of coupling rates to different modes can lead to improved conversion efficiencies and

Creating and probing electron whispering-gallery modes in graphene [PDF]
Science, 2015 A circular route to confine electrons Physical barriers are used to confine waves. Whether it is harbor walls for sea waves, a glass disk for light, or the “whispering gallery” circular chamber walls in St.

Spherical whispering‐gallery‐mode microresonators
Laser & Photonics Reviews, 2010 AbstractWhispering‐gallery modes (WGM) on a spherical surface were first described by Lord Rayleigh at the beginning of the last century, but only after the invention of laser did they start to have some scientific relevance and only during the last two decades there has been a substantial move towards real devices and practical applications.

Design of microcavity resonators for single-atom detection [PDF]
, 2007 Whispering gallery modes of a microdisk resonator are useful for the optical detection of single rubidium and cesium atoms near the surface of a substrate. Light is coupled into two high-Q whispering-gallery modes of the disk which can provide attractive

Carrier-induced refractive index change observed by a whispering gallery mode shift in GaN microrods
New Journal of Physics, 2015 Vertical oriented GaN microrods were grown by metal-organic vapor phase epitaxy with four different n-type carrier concentration sections above 10 ^19 cm ^−3 along the c -axis.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing
Sensing and Bio-Sensing Research, 2019 In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle

Topological whispering gallery modes in two-dimensional photonic crystal cavities.
Optics Express, 2018 Utilizing the robust transport properties of the topological photonic crystal interface, we experimentally realize two-dimensional topological photonic crystal cavities, where discrete whispering gallery modes can propagate unidirectionally along the ...

FDTD modelling of mid infrared disk lasers [PDF]
, 2007 This paper presents 2D FDTD modelling of a disk resonator that could be used as a disk laser. Results are shown for mode spacing and good agreement with a simple Whispering Gallery Mode model is observed.
