Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
An antibacterial coating based on a polymer/sol-gel hybrid matrix loaded with silver nanoparticles
(Springer, 2011)
Artículo / Artikulua,
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid ...
Mode transitions and thickness measurements during deposition of nanoscale TiO2 coatings on tilted fiber Bragg gratings
(IEEE, 2022)
Artículo / Artikulua,
The mode transition is a phenomenon observed in
thin film coated long period fiber gratings (LPGs) and singlemode multimode single-mode (SMS) fibers for certain values of
the coating thickness and refractive index, ...
A comparative study of two different approaches for the incorporation of silver nanoparticles into layer-by-layer films
(Springer, 2014)
info:eu-repo/semantics/article,
In this work, a comparative study about the incorporation of silver nanoparticles (AgNPs) into thin films is presented
using two alternative methods, the in situ synthesis process and the layer-by-layer embedding deposition ...
Improving the width of lossy mode resonances in a reflection configuration D-shaped fiber by nanocoating laser ablation
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The full width at half maximum (FWHM) of lossy mode resonances (LMRs) in the optical spectrum depends on the homogeneity of the thin film deposited. In this Letter, a method for improving the FWHM is applied for an LMR ...
Optimization in nanocoated D-shaped optical fiber sensors
(Optical Society of America, 2017)
Artículo / Artikulua,
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here,
we show that the full width at half minimum (FWHM) of lossy mode resonance can be
reduced by optimizing the nanocoating width, thickness and ...
Generation of lossy mode resonances with absorbing thin-films
(IEEE, 2010)
Artículo / Artikulua,
The generation of lossy mode resonances with
absorbing thin-films is analyzed with electromagnetic theory. The
main differences with surface plasmon resonances are presented
and some rules are given towards an optimum ...
Deposition of coatings on long-period fiber gratings: tunnel effect analogy
(Springer, 2006)
Artículo / Artikulua,
The sensitivity of Long-period fiber gratings (LPFGs), coated with high-refractive-index thin
film overlays, to the refractive index and the thickness of the overlay, and to the ambient refractive
index, can be enhanced ...
Long period fiber gratings with overlay of variable refractive index
(IEEE, 2005)
Artículo / Artikulua,
A theoretical analysis is presented of a long-period
fiber grating (LPFG) with an overlay of variable refractive index.
The highest sensitivity of the resonance wavelengths to variations
in the refractive index of the ...
Generation of lossy mode resonances (LMR) using perovskite nanofilms
(Chinese Academy of Sciences, 2024)
Artículo / Artikulua,
The results presented here show for the first time the experimental demonstration of the fabrication of lossy mode resonance (LMR) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin films ...
