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

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

The interest in organic–inorganic hybrids as materials for optics and photonics started more
than 25 years ago and since then has known a continuous and strong growth. The high …

Whispering gallery mode resonators (WGMRs) have achieved significant results due to their
unique properties such as extremely small mode volume, ultra‐high quality (Q) factor, fast …

We carry out simulations based on a four-layer Mie model to systematically analyze the
sensing performance of ring resonator chemical vapor sensors. Two sensor configurations …

We develop a versatile, compact, and sensitive fiber-based optical Fabry-Pérot (FP) gas
sensor. The sensor probe is composed of a silver layer and a vapor-sensitive polymer layer …

We develop rapid chemical-vapor sensors based on optofluidic ring resonators (OFRRs).
The OFRR is a glass capillary whose circular wall supports the circulating waveguide modes …

Integrated opto-chemical sensors present great advantages in comparison to the current lab
equipment. They bring portability, reduced costs, facilitate in-situ measurements, as well as …

On-chip devices for absorption spectroscopy and Raman spectroscopy have been
developing rapidly in the last few years, triggered by the growing availability of compact and …

A PbS quantum dots (QDs) fiber amplifier was fabricated and characterized by using a
standard single mode fiber (SMF) coupler. The fiber amplifier was fabricated by coating PbS …
