Whispering-Gallery Sensors. [PDF]
Matter, 2020 Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a microscale volume for long periods of time, strongly enhance light-matter interactions, making them an ideal platform for photonic sensors. One of the features of WGM sensors is their capability to respond to environmental perturbations that influence the optical ...

Whispering Gallery Mode Thermometry [PDF]
Sensors, 2016 This paper presents a state-of-the-art whispering gallery mode (WGM) thermometer system, which could replace platinum resistance thermometers currently used in many industrial applications, thus overcoming some of their well-known limitations and their ...

Whispering Gallery‐Mode Microdroplet Tensiometry [PDF]
Advanced Photonics Research, 2021 Droplets are ideally suited to support high‐Q‐factor whispering gallery modes (WGMs) due to their perfectly smooth surface. WGMs enable extremely precise measurements of the droplet properties such as size and shape.

Non-Hermitian topological whispering gallery
Nature, 2021 In 1878, Lord Rayleigh observed the highly celebrated phenomenon of sound waves that creep around the curved gallery of St Paul's Cathedral in London1,2. These whispering-gallery waves scatter efficiently with little diffraction around an enclosure and have since found applications in ultrasonic fatigue and crack testing, and in the optical sensing of ...

Photonic lenses with whispering gallery waves at Janus particles
Opto-Electronic Science, 2022 We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder.

Whispering gallery mode sensors [PDF]
Advances in Optics and Photonics, 2015 We present a comprehensive overview of sensor technology exploiting optical whispering gallery mode (WGM) resonances. After a short introduction we begin by detailing the fundamental principles and theory of WGMs in optical microcavities and the transduction mechanisms frequently employed for sensing purposes.

Spatial Multiplexing of Whispering Gallery Mode Sensors
Sensors, 2023 Whispering gallery mode resonators have proven to be robust and sensitive platforms for the trace detection of chemical and/or biological analytes. Conventional approaches using serially addressed resonators face challenges in simultaneous multi-channel (

Reconfigurable symmetry-broken laser in a symmetric microcavity
Nature Communications, 2020 The directional lasing emission in whispering gallery microcavities typically resorts to breaking the structure symmetry. Here the authors demonstrate a reconfigurable symmetry-broken microlaser in a symmetric ultrahigh-Q whispering gallery microcavity ...

Trapping a single atom in the evanescent field of a WGM-resonator [PDF]
EPJ Web of Conferences, 2022 We demonstrate the trapping of single atoms in the evanescent field of a whispering-gallery-mode (WGM) resonator with a standing wave optical dipole trap. We present our progress towards an improved trap loading scheme.
