A range of optical fibre-based sensors for the measurement of ethanol, primarily in aqueous
solution, have been developed and are reviewed here. The sensing approaches can be …

Fiber-optic evanescent wave (FOEW) sensors are promising in pollutant detection and
evaluation of water quality because of their high resistance to corrosion, smart structure, anti …

In the past century, industrial and technological improvements lead to a significant increase
in water contamination with aqueous solutions of heavy metals ions. In this regard, the …

Tuberculosis is a widespread disease all over the world. Early diagnosis plays a crucial role
in the treatment of patients and can reduce the mortality rate. A new biosensor based on a …

The work describes the refractive index sensor which can be used particularly for
tuberculosis blood samples. The possibility of this approach is pertained by the ring core …

A refractometric and low-temperature sensor based on a simple one-dimensional binary
photonic crystal is investigated. The photonic crystal consists of alternating layers of …

An optical fiber ring laser (FRL) cavity-based sensitive temperature and salinity sensor is
proposed and experimentally demonstrated. The sensor consists of a Sagnac loop with a …

A fiber ring laser sensor setup utilizing fiber Bragg gratings (FBGs) for simultaneous
measurement of ambient temperature and relative humidity (RH) is presented. Two FBGs …

In this paper, we analyse a novel photonic sensor utilising mode-transition in hexagonal
photonic crystal fiber (HPCF) to monitor the ethanol content in an ethanol-gasoline blend …

Estimation models for the surrounding refractive index response of EFBGs were developed
from computer simulations and tested on experimental data. Numerical simulations were …
