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 …

Thanks to the peculiarities of optical fiber and its ability to be combined with
nanotechnology, precise and accurate measurements of the changes in optical properties …

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 …

While a number of literature reviews have been published in recent times on the
applications of optical fibre sensors in smart structures research, these have mainly focused …

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 …

The method and the required installations for fabricating tapered long-period fiber gratings
can be simpler than that of standard fiber Bragg gratings, and the fabrication process is …

Sensitivity of fiber cladding modes coupled with long-period gratings (LPGs) in photonic
crystal fiber (PCF) are investigated with respect to external conditions such as temperature …

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 …

We investigate a periodically micro-tapered fiber grating for simultaneous measurement of
strain and temperature. The fundamental core mode can be coupled to the cladding mode …

Optical fibre sensors have conventionally been made of silica. Polymers however have a
much lower Young's modulus and higher elastic limit than silica, and can be incorporated …
