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 ...
Hybrid Raman‑erbium random fiber laser with a half open cavity assisted by artificially controlled backscattering fiber refectors
(Springer Nature, 2021)
Artículo / Artikulua,
A hybrid Raman-erbium random fber laser with a half-open cavity assisted by chirped artifcially
controlled backscattering fber refectors is presented. A combination of a 2.4 km-long dispersion
compensating fber with two ...
Quasi-distributed vibration analysis of a cantilever beam using OFDR and weak reflectors
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This work evaluates the performance of a quasi-distributed in-line velocimeter based on OFDR and weak reflectors to measure vibration every 10 cm, using a cantilever beam under free-end damping and during an impact-hammer test.
Láser random de fibra óptica asistido por reflectores de fibra con retrodispersión controlada artificialmente

Vertically coupled InP/InGaAsP microring lasers using a single epitaxial growth and singleside lithography
(IEEE, 2020)
info:eu-repo/semantics/article,
The experimental demonstration of vertical microring lasers requiring only one single epitaxial growth and two single-side lithographic steps is presented, in what is the simplest fabrication scheme for such devices published ...
Anomalous relative intensity noise transfer in ultralong random fiber lasers
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
We present, for the first time, an experimental demonstration of RIN noise transfer dampening at low frequencies in random distributed feedback ultralong Raman fibre lasers based on conventional telecommunication fibres. ...
Quasi-distributed vibration sensing based on weak reflectors and STFT demodulation
(IEEE, 2020)
Artículo / Artikulua,
In this work, a new system is proposed for quasi-distributed vibration sensing based on the Doppler effect. The setup employs an optical frequency domain reflectometer (OFDR) and an array of weak reflectors. The short-time ...
Multiparameter sensor based on a multiinterferometric serial configuration for temperature and strain measurements

Artículo / Artikulua,
In this work, a multi-parameter point sensor based
on the combination of Fabry-Perot (FP) and the anti-resonant
(AR) reflecting guidance in cascade configuration is proposed and
experimentally demonstrated. This structure, ...
Gamma radiation-induced effects over an optical fiber laser: towards new sensing applications
(MDPI, 2020)
info:eu-repo/semantics/article,
In the present work, the effect of gamma radiation on the performance of different types of erbium-doped fibers (EDFs) when they are used in a fiber ring cavity (FRC) configuration is studied. Several pieces of commercial ...
