ECOAL project: delivering solutions for integrated monitoring of coal-related fires supported on optical fiber sensing technology
(MDPI, 2017)
Artículo / Artikulua,
The combustion of coal wastes resulting from mining is of particular environmental concern, and the importance of proper management involving real-time assessment of their status and identification of probable evolution ...
Ultra-long (290 km) remote interrogation sensor network based on a random distributed feedback fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
In this work, an interferometric sensor has been interrogated 290 km away from the
monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been
attained by employing a double-pumped ...
Vertically coupled microring resonators using one epitaxial growth step and single-side lithography
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
A new concept for the fabrication of integrated microring
resonators, requiring only one single epitaxial growth and two single-side
lithographic steps, is proposed in what is the simplest fabrication scheme
for vertical ...
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 ...
Single-longitudinal mode laser structure based on a very narrow filtering technique
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A narrow filtering technique based on the spectral overlapping of
two uniform FBGs and applied to obtain a Single Longitudinal Mode
(SLM) laser is proposed and demonstrated in this work. The two FBGs are
spectrally ...
Compact and highly-efficient polarization independent vertical resonant couplers for active-passive monolithic integration
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
Compact low-loss polarization independent vertical coupling
between a 1.55 μm InGaAsP bulk active waveguide and a passive
waveguide based on bimodal interference is presented. Simulation results
show low coupling loss (<0.1 ...
WDM bi-directional transmission over 35 km amplified fiber-optic bus network using Raman amplification for optical sensors
(Optical Society of America, 2005)
info:eu-repo/semantics/article,
We demonstrate a novel distributed fiber Raman amplified bus
topology used for WDM transmission over 35 km of single-mode fiber by
use of a multiwavelength Raman pump laser and eight Fiber Bragg gratings
(FBGs). This ...
Comparison of wavelength-division-multiplexed distributed fiber Raman amplifier networks for sensors
(Optical Society of America, 2006)
info:eu-repo/semantics/article,
A novel distributed fiber Raman amplified star topology used for
optical sensor wavelength-division multiplexing is proposed. The
performance of this star configuration is compared to an optically amplified
bus topology. ...
