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 ...
Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM
(IEEE, 2016)
info:eu-repo/semantics/article,
In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ...
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 ...
Real-time FFT analysis for interferometric sensors multiplexing
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this paper, a theoretical and experimental study of two interferometric sensor multiplexing schemes has been carried out by means of the fast Fourier transform (FFT) analysis. This work addresses one of the main drawbacks ...
All-PM fiber loop mirror interferometer analysis and simultaneous measurement of temperature and mechanical vibration
(IEEE, 2018)
info:eu-repo/semantics/article,
In this work, a new all-polarization maintaining (PM) fiber loop mirror interferometer is proposed and validated as temperature and mechanical vibration sensor. The scheme employs the arms of a PM coupler as communication ...
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 ...
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 ...
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 ...
