Aptasensors Based on Whispering Gallery Mode Resonators [PDF]
Biosensors, 2016 In this paper, we review the literature on optical evanescent field sensing in resonant cavities where aptamers are used as biochemical receptors. The combined advantages of highly sensitive whispering gallery mode resonator (WGMR)-based transducers, and of the unique properties of aptamers make this approach extremely interesting in the medical field,

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.

Controlled tuning of whispering gallery modes of GaN/InGaN microdisk cavities [PDF]
Applied Physics Letters, 2011 Controlled tuning of the whispering gallery modes of GaN/InGaN {\mu}-disk cavities is demonstrated. The whispering gallery mode (WGM) tuning is achieved at room temperature by immersing the {\mu}-disks in water and irradiating with ultraviolet (UV) laser.

Solid and hollow whispering gallery mode resonators for all optical switch [PDF]
EPJ Web of ConferencesWhispering-gallery-modes resonators (WGMR) are effective switching devices when either coated or filled with non-linear material. We present examples of all-optical switching of hybrid WGM using polyfluorene, a methacrylate azobenzene and an acrylate ...

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 potential for providing lower measurement uncertainty.

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.
