Achieving a new generation of enhanced sensors requires the development of structures
that result from the fusion of different concepts and effects. In this paper, we combine a …

We propose two types of temperature-compensated all-fiber sensors based on a novel laser-
machined Fabry–Perot interferometer (FPI) whose sensitivity is adjusted by controlling the …

We demonstrated an optical fiber sensor based on a cascaded fiber Fabry-Perot
interferometer (FPI)-regenerated fiber Bragg grating (RFBG) for simultaneous measurement …

An ultracompact fiber sensor probe based on cascaded polymer microspheres with high
sensitivity is proposed for simultaneously measuring the transverse load and the …

A hollow core fiber (HCF) is spliced with a single-mode fiber, and then, the end face of the
HCF is etched to form a microsphere interferometer for measuring gas pressure and …

The use of graphene oxide-based coatings on optical fibers are investigated, aiming to tune
the reflectivity of optical fiber surfaces for use in precision sensing devices. Graphene oxide …

We propose a fiber-based environmental sensor that exploits the reflection-phase-shift
tunability provided by the use of layered coatings composed of dielectric slabs spaced by …

A hollow core fiber (HCF) is spliced with a single-mode fiber, and then the end face of HCF
is discharged to form a microsphere interferometer for measuring gas pressure and …
