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 ...
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 ...
A comparative study between SMS interferometers and lossy mode resonace optical fiber devices for sensing applications

Contribución a congreso / Biltzarrerako ekarpena,
Optical fiber sensors are of great interest due to their intrinsic advantages over electronic sensors. In this work, the
sensing characteristics of two different and novel optical fiber devices are compared, after ...
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 ...
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 ...
Vibration detection using optical fiber sensors

Condition monitoring of heavy electromechanical equipment is commonly accomplished in the industry using vibration analysis.
Several techniques, mainly based on capacitive and piezoelectric accelerometers, have been applied ...
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 ...
All fiber interferometer for ice detection
(Optica Publishing Group, 2018)
