Fiber cavity ring down and gain amplification effect
(Springer Nature, 2016)
info:eu-repo/semantics/article,
The effect of an erbium-doped fiber amplifier (EDFA) placed inside the fiber ring of a cavity ring down (CRD) configuration is studied. The limitations and advantages of this configuration are discussed, and the study of ...
Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a novel concept for hybrid networks that combine
point and distributed Brillouin sensors in a cost-effective architecture that
also deploys remote distributed Raman amplification to extend the sensing
range. A ...
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 ...
Highly-efficient fully resonant vertical couplers for InP active-passive monolithic integration using vertically phase matched waveguides
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A new active-passive monolithic integration approach for
photonic components based on vertical evanescent coupling is presented.
Two vertically stacked waveguides are used in order to provide full
resonant power transfer ...
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, ...
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 ...
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 ...
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 ...
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 ...
