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 ...
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 ...
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 ...
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 ...
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, ...
A comparative study in the sensitivity of optical fiber refractometers based on the incorporation of gold nanoparticles into layer-by-layer films
(Exeley, 2015)
info:eu-repo/semantics/article,
In this work, optical fiber refractometers based on the successive incorporation of gold nanoparticles have been fabricated by means of the Layer-by-Layer Embedding (LbL-E) deposition technique. This enables the apparition ...
Simultaneous measurement of humidity and temperature based on a partially coated optical fiber long period grating
(Elsevier, 2016)
info:eu-repo/semantics/article,
A humidity and temperature optical fiber sensor based on a long-period grating (LPG), which can provide simultaneous response to both magnitudes, is proposed and demonstrated via experiments. Previously, the LPG was fully ...
