Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

Humidity and moisture sensing is becoming increasingly important in industry and through a
wide spectrum of applications and a review of research activity in the field across a range of …

An evanescent wave optical fiber biosensor based on titania–silica-coated long period
grating (LPG) is presented. The chemical overlay, which increases the refractive index (RI) …

A single-mode tapered fiber optic biosensor was utilized for real-time monitoring of the
Escherichia coli (E. coli K-12) growth in an aqueous medium. The applied fiber tapers were …

An optical fibre long period grating (LPG) based carbon dioxide (CO 2) sensor coated with
HKUST-1, a material from the metal organic framework family, functional coating is …

An optical fibre long period grating (LPG) modified with a thin film of ZIF-8, a zeolitic
immidazol framework material and a subgroup of metal organic framework family, was …

We demonstrate a sensitive DNA biosensor based on a long period grating (LPG) formed by
a photolithograph process on the surface of a side-polished fiber. The biomolecules of the …

Long period fiber gratings produced by the electric arc technique have found an increasing
interest by the scientific community due to their ease to fabricate, virtually enabling the …

In this paper, we discuss an impact of thin titanium dioxide (TiO_2) coatings on refractive
index (RI) sensitivity and biofunctionalization of long-period gratings (LPGs). The TiO_2 …

A review of optical fibre devices employing nano-structured coatings is presented. Active
and passive coatings, deposited using the Langmuir–Blodgett and electro-static self …
