Photonic crystal fibers for sensing applications
(Hindawi Publishing Corporation, 2012)
Artículo / Artikulua,
Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers ...
Robust fiber-optic sensor networks
(Springer, 2012)
Artículo / Artikulua,
The ability to operate despite failure will become increasingly important as the use of optical sensor networks grows, and the amount of sensing information to be handled by a sensor network is increasing, especially for ...
Dual stage ytterbium doped fiber laser in MOPA configuration
(Bentham Open, 2012)
Artículo / Artikulua,
We report the experimental demonstration of an Ytterbium doped fiber laser (YDFL) composed by two stages in cascade. Two sorts of Ytterbium doped fiber (YDF) with different concentration have been used. A proper characterization ...
Remote-time division multiplexing of bending sensors using a broadband light source
(Hindawi Publishing Corporation, 2012)
Artículo / Artikulua,
This work experimentally demonstrates a remote sensing network which interrogates bending sensors using time-division multiplexing techniques and a broadband light source. The bending sensors are located 50 km away from ...
Micro-displacement sensor based on a hollow-core photonic crystal fiber
(MDPI, 2012)
Artículo / Artikulua,
A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment of hollow-core ...
Application of remote power-by-light switching in a simplified BOTDA sensor network
(MDPI, 2013)
Artículo / Artikulua,
We propose and demonstrate the use of spatial multiplexing as a means to reduce the costs of distributed sensing networks. We propose a new scheme in which remote power-by-light switching is deployed to scan multiple ...
An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber
(MDPI, 2013)
Artículo / Artikulua,
A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of the sensing ...
Compact optical fiber lasers and optical fiber sensors assisted by femtosecond laser inscription of plane-by-plane FBGs
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Development of a high temperature sensor based on optical fiber l aser generated from a cavity of reduced dimensions (43 mm) in Er-doped fiber. The mirror FBGs have been inscribed with femtosecond laser using the slit beam ...
In-field torsion measurements on solar trackers using fiber optic sensors
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
In-field torsion measurements on solar trackers using fiber Bragg gratings are presented. 45 FBG sensors have been deployed in an operational solar energy plant to study the mechanical response of the structure to wind.
Enhanced optical fiber lasers and optical fiber sensors assisted by micro-drilled optical fibers
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are
demonstrated. Strain sensitivity improved more than one order of magnitude in comparison
with FBG sensors using a 50 μm-waist micro-drilled taper ...
