The tilted fiber Bragg grating (TFBG) is a new kind of fiber-optic sensor that possesses all the
advantages of well-established Bragg grating technology in addition to being able to excite …

Surface plasmon resonance (SPR) optical fiber sensors can be used as a cost-effective and
relatively simple-to-implement alternative to well established bulky prism configurations for …

Optical measurement of mechanical parameters is gaining significant commercial interest in
different industry sectors. Torsion, twist and rotation are among the very frequently measured …

The conventional single-angle tilted fiber Bragg grating (TFBG) can only excite a certain
range of cladding modes, limiting it for refractive index (RI) measurement in a wide range. In …

We demonstrate a directional curvature sensor based on tilted few-mode fiber Bragg
gratings (FM-FBGs) inscribed by a UV laser. The eigenmodes of LP_01 and LP_11 mode …

This paper proposes a new approach of demodulating the spectra of tilted fiber Bragg
grating (TFBG) based refractive-index (RI) sensor by employing convolutional neural …

A novel fiber-optic sensor is demonstrated based on half-tapered single-mode-multimode-
single-mode fiber structure, which consists of the multimode interferometer (MMI) and Mach …

We propose a high-performance vector torsion sensor based on an in-fiber Mach-Zehnder
interferometer (MZI), which consists of a straight waveguide inscribed in the core-cladding …

The tilted fiber grating (TFG) is a special grating whose grating planes are slanted or blazed
relative to the fiber axis. These tilts in the planes break the cylindrical symmetry of the fiber …
