The past decade saw the emergence of new temperature sensors that have the potential to
disrupt a century-old measurement infrastructure based on resistance thermometry. In this …

Abstract Fiber Bragg Gratings or FBGs have achieved significant attention towards sensing
and communication applications due to their outstanding advantages. Due to its high …

A fibre optic sensor capable of discriminating between temperature and strain, using a
single fibre Bragg grating, is presented. The technique exploits the core–cladding mode …

The fabrication, characterization and encapsulation of a fiber optic temperature sensor
based upon a micro Fabry–Perot (FP) cavity is presented. The FP cavity is formed between a …

A high-resolution and large-dynamic-range temperature sensor adopting a pair of fiber
Bragg grating as Fabry–Pérot cavity (FBG-FP) and laser frequency dither locking method is …

This paper presents a thorough analysis on the temperature dependence of the thermo-optic
coefficient, dn/d T, of four bulk annealed pure-silica glass samples (type I—natural quartz …

In recent years photonic thermometers—temperature sensors based on optical frequency
measurement which exploit the thermo-optic effect to translate thermal changes into …

We demonstrated a linear-cavity fiber laser using a fiber Bragg grating (FBG) fabricated by
femtosecond laser and a Sagnac loop as cavity mirrors. The temperature sensing response …

In this paper we derived an expression that allows the determination of the thermo-optic
coefficient of weakly-guiding germanium-doped silica fibers, based on the thermal behavior …

Fiber optic sensors (FOS) in long-term structural health monitoring (SHM) have drawn
significant attention due to their pivotal role in detecting defects and measuring structural …
