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 ...
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 ...
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 ...
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 ...
Fiber optic sensor networks
(Elsevier, 2013)
info:eu-repo/semantics/article,
One of the main goals in fiber optic sensor technology is to multiplex together a high number of sensorsin the same network in order to share expensive terminal equipment and develop a system including multiple measuring ...
Stabilization of dual-wavelength erbium doped ring fiber lasers by single-mode operation
(IEEE, 2010)
info:eu-repo/semantics/article,
In this work, a novel single-longitudinal-mode (SLM)
dual-wavelength laser configuration is proposed and demonstrated. This laser is based on ring resonators, and employs fiber
Bragg gratings to select the operation ...
Experimental optimization in terms of power stability and output power of highly Er-doped fiber lasers with single and hybrid cavities
(Taylor & Francis, 2010)
info:eu-repo/semantics/article,
In this article, the output power stability of several different highly erbiumdoped fiber ring lasers, as a function of the laser parameters, is experimentally
investigated. The study is focused on the optimization of ...
