Optical fiber sensors based on nanostructured materials for environmental applications
(2014)
Tesis doctoral / Doktoretza tesia,
La contaminación ambiental es la presencia de agentes físicos, químicos o biológicos presentes en el agua, suelo y aire; siendo perjudiciales para la salud de las personas, así como para la vida vegetal y animal. Las ...
All fiber interferometer for ice detection
(Optica Publishing Group, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents an etched single-mode - multimode - single-mode structure that detects the solid-to-liquid change of state of the water due to an increased refractive index sensitivity within the 1.308 - 1.321 RIU range
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 ...
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 ...
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, ...
Contribution to the development of functional nanostructured coatings based on silver nanoparticles
(2014)
Tesis doctoral / Doktoretza tesia,
Esta tesis se centra en la síntesis de nanopartículas de plata (AgNPs) y su posterior incorporación en recubrimientos delgados usando dos métodos alternativos: el proceso de síntesis in situ (ISS) de AgNPs y la técnica de ...
Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction
(IEEE, 2015)
Artículo / Artikulua,
We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...
Overcoming non-local effects and Brillouin threshold limitations in Brillouin optical time domain sensors
(IEEE, 2015)
Artículo / Artikulua,
We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis
(BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the
deployed sensing fiber ...
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 ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
