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 …

We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

Humidity measurement is one of the most significant issues in various areas of applications
such as instrumentation, automated systems, agriculture, climatology and GIS. Numerous …

Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a
microscale volume for long periods of time, strongly enhance light-matter interactions …

A wide range of applications such as health, human comfort, agriculture, food processing
and storage, and electronic manufacturing, among others, require fast and accurate …

Measuring humidity in dynamic situations calls for highly sensitive fast response sensors.
Here we report, a humidity sensor fabricated using solution processed supramolecular …

Solar‐blind deep ultraviolet (DUV) photodetectors have been a hot topic in recent years
because of their wide commercial and military applications. A wide bandgap (4.68 eV) of …

One-dimensional photonic crystals (1DPhCs) combined with a thin Au layer are designed to
show up the Tamm resonances with potential sensor applications. For two 1DPhCs …

We report on a highly sensitive measurement of the relative humidity (RH) of moist air using
both the surface plasmon resonance (SPR) and Bloch surface wave resonance (BSWR) …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …
