Whispering Gallery‐Mode Microdroplet Tensiometry [PDF]

open access: yesAdvanced 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.

Whispering gallery modes in coated silica microspheres

open access: yesSPIE Proceedings, 2012
Silica microspheres were made by melting the tip of a standard telecom fiber and were coated with a 70SiO2 - 30 HfO2 sol-gel derived glass activated by 0.3 mol % of Er3+ ions. The samples were coated using a dip coating apparatus. The thickness of the coating was estimated to be around 1 μm.

Whispering-gallery-mode sensors for biological and physical sensing [PDF]

open access: yes, 2021
The term whispering gallery mode (WGM) was first introduced to describe the curvilinear propagation of sound waves under a cathedral dome. The physical concept has now been generalized to include light waves that are continuously reflected along the ...

Whispering Gallery Mode Thermometry [PDF]

open access: yesSensors, 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]

open access: yesAdvances 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.

Effects of Nanocylinders on the Whispering Gallery Modes in a Microcylinder. [PDF]

open access: yesSensors (Basel), 2016
Optical biosensors have been studied extensively for the detection and characterization of biological entities, such as viruses, bacteria, and biomolecules. A two-dimensional (2D) microcylinder resonator ( Q ∼ 2 × 10 5 ) was designed, and the effects of a nanocylinder on the whispering gallery modes (WGMs) were examined numerically.

Aptasensors Based on Whispering Gallery Mode Resonators [PDF]

open access: yesBiosensors, 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,

Reconfigurable Liquid Whispering Gallery Mode Microlasers [PDF]

open access: yesScientific Reports, 2016
AbstractEngineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface ...

Thermometry based on Whispering Gallery Mode resonators [PDF]

open access: yes, 2012
Whispering gallery (WG) mode resonators were studied since 1980s for precision clock oscillators and for cavity quantum electrodynamics studies. They are a kind of stable, high Q, microwave resonators where a symmetric dielectric medium, such as a ...
