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 ...
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 ...
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 ...
Suspended-core fiber Sagnac combined dual-random mirror Raman fiber laser
(Optical Society of America, 2011)
info:eu-repo/semantics/article,
In the present work, a multiwavelength fiber laser based in the
combination of a double-random mirror and a suspended-core Sagnac
interferometer is presented. The double-random mirror acts by itself as a
random laser, ...
Multiplexing of six micro-displacement suspended-core Sagnac interferometer sensors with a Raman-Erbium fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
This work experimentally demonstrates a long-range optical
fiber sensing network for the multiplexing of fiber sensors based on
photonic crystal fibers. Specifically, six photonic crystal fiber sensors
which are based ...
High resolution polarization-independent highbirefringence fiber loop mirror sensor
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
In this work, two all polarization-maintaining (PM) highbirefringence
(Hi-Bi) fiber loop mirrors (FLM) which are immune to
external polarization perturbations are validated both theoretically and
experimentally. Simplified ...
Random fiber lasers: application to fiber optic sensors networks
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities ...
Micro-displacement sensor combined with a fiber ring interrogated by an optical time-domain reflectometer
(IEEE, 2014)
info:eu-repo/semantics/article,
A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an OTDR is presented. The sensor configuration is characterized for measuring both longitudinal ...
Internal modulation of a Random fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were ...
