With the increasing of water pollution problems, detection of heavy metal ion concentration
in water environment becomes significant. Optical fiber sensor, with its particular advantages …

Compact interferometers based on waveguiding structures have found countless
applications in refractive index measurements, chemical sensing, as well as temperature …

A salinity sensor employing photonic crystal fiber is designed for measuring the
concentration of salt in sea water. The sea water sample is infiltrated into one of the air holes …

In this paper, a review of multicore fiber interferometric sensors is given. Due to the
specificity of fiber structure, ie, multiple cores integrated into only one fiber cladding …

Forensic chemistry is the application of analytical chemistry to forensic analysis and is today
one of the hot topics in the scientific literature as it can provide valuable information …

We review our works on Fabry-Perot (FP) interferometric fiber-optic sensors with various
applications. We give a general model of FP interferometric optical fiber sensors including …

A humidity sensor made of tapered plastic optical fiber (POF) coated with agarose gel or
hydroxyethylcellulose/polyvinylidenefluoride (HEC/PVDF) detects humidity from the change …

In this study, a new type of highly sensitive fiber-optic Fabry–Perot interferometer (FFPI) is
proposed with a high sensitivity on a wide refractive index (RI) measurement range based …

In this paper, we demonstrate highly sensitive refractive index (RI) sensing based on
multicore coupled structures. Specifically, we use a seven-core fiber (SCF) as the sensing …

This review is focused on microstructured optical fiber sensors developed in recent years for
liquid RI sensing. The review is divided into three parts: the first section introduces a general …
