Optical fibre sensors (OFS), as a result of their unique properties such as small size, no
interference with electromagnetic radiation, high sensitivity and the ability to design …

Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved
features beyond what conventional optical fibers can offer. Due to their unique geometric …

This paper presents a systematic review of long period fiber gratings (LPFGs) written by the
CO 2 laser irradiation technique. First, various fabrication techniques based on CO 2 laser …

Photonic crystal fiber sensors have potential application in environmental monitoring,
industry, biomedicine, food preservation, and many more. These sensors work based on …

A review of optical fiber sensing demonstrations based on photonic crystal fibers is
presented. The text is organized in five main sections: the first three deal with sensing …

A force sensor apparatus includes a tube portion having a plurality of radial ribs and at least
one fiber optic strain gauge positioned over each of the plurality of radial ribs. The strain …

In one embodiment, a force sensor apparatus is provided including a tube portion having a
plurality of radial ribs and at least one fiber optic strain gauge positioned over each rib of the …

The authors report a highly sensitive (∼ 2.8 pm∕ μ ε) wavelength-encoded strain sensor
made from a piece of photonic crystal fiber (PCF) spliced to standard fibers. The authors …

We study the sensitivity of fiber grating sensors in the applications of strain, temperature,
internal label-free biosensing, and internal refractive index sensing. New analytical …

Preface few techniques have had an impact on society that can compare to that of fiber
optics. These tiny hair-sized glass wires have deeply transformed, at the dawn of this third …
