Optical fiber sensors based on nanoparticle-embedded coatings
(Hindawi Publishing Corporation, 2015)
Artículo / Artikulua,
The use of nanoparticles (NPs) in scientific applications has attracted the attention of many researchers in the last few years. The use of NPs can help researchers to tune the physical characteristics of the sensing coating ...
Tapered single-mode optical fiber pH sensor based on lossy mode resonances generated by a polymeric thin-film
(IEEE, 2012)
Artículo / Artikulua,
Lossy mode resonances can be generated with certain polymeric nanostructures, such as those obtained with a multilayered assembly of poly(allylamine hydrochloride) and poly (acrylic acid). This coating is adsorbed by the ...
An optimized method based on digitalized Lissajous curve to determine lifetime of luminescent materials on optical fiber sensors
(Hindawi, 2016)
Artículo / Artikulua,
A method is proposed to determine lifetime of luminescent emissions based on the phase shift measurement employing the digitalized Lissajous representation: this diagram has been typically used with analogical algorithms, ...
Generation of lossy mode resonances by deposition of high-refractive-index coatings on uncladded multimode optical fibers
(IOP Publishing Ltd, 2010)
Artículo / Artikulua,
A comparative study of lossy mode resonances generated by depositing two different materials
is presented. The two materials selected are indium tin oxide (ITO) and indium oxide. The two
materials present different ...
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 ...
Sensors based on thin-film coated cladding removed multimode optical fiber and single-mode multimode single-mode fiber: a comparative study
(Hindawi Publishing Corporation, 2015)
Artículo / Artikulua,
Two simple optical fibre structures that do not require the inscription of a grating, a cladding removed multimode optical fibre
(CRMOF) and a single-mode multimode single-mode structure (SMS), are compared in terms of ...
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
(Elsevier, 2018)
Artículo / Artikulua,
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
Nanodeposition of materials with complex refractive index in long period fiber gratings
(IEEE, 2005)
Artículo / Artikulua,
An overlay of higher refractive index than the
cladding is deposited on a Long Period Fiber Grating (LPFG).
This permits to improve in a great manner the sensitivity of the
device to ambient and overlay refractive index ...
Influence in cladding mode distribution of overlay deposition on long-period fiber gratings
(Optical Society of America, 2006)
Artículo / Artikulua,
A thin overlay of higher refractive index than that of the cladding of a long-period fiber grating induces in
cladding modes strong variations in effective index, mode profile, cross-coupling coefficient with the core ...
