Development of a water flow and velocity optical fiber sensor for field testing
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels.
Micro-displacement sensor based on hollow core fiber interferometers
(Optica, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
An interferometric sensor based on hollow core fibers for the measurement of micro-displacement has been designed. Its characterization has resulted in a linear response, suggesting its application in pressure sensors.

Stable L-band fiber laser sensor using a backscattering-based multimode fiber reflector
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A new and highly stable L-band fiber laser for sensing is demonstrated. An emission line at 1575.47 nm, was achieved using a special reflector. Good strain sensitivity, optical signal to noise ratio and output power stability ...
High performance fiber laser resonator for dual band (C and L) sensing
(IEEE, 2022)
Artículo / Artikulua,
This work presents an experimental analysis and comparison of the performance of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror both in C- and L-band. Single-wavelength emission ...
C and L band fiber lasers enhanced by ultrafast laser inscribed artificial backscatter reflectors
(Optica, 2022)
Artículo / Artikulua,
This letter presents an experimental comparison between two linear-cavity erbiumdoped fiber lasers (EDFL) assisted by two different artificial backscatter fiber-based reflectors.
Both reflectors were inscribed by femtosecond ...
Effect of linewidth on the relative intensity noise in random distributed feedback raman fiber lasers
(MDPI, 2022)
Artículo / Artikulua,
We experimentally explore the relation between spectral linewidth and RIN transfer in half-open cavity random distributed feedback Raman lasers, demonstrating for the first time the possibility of adjusting the pump-to-signal ...
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.
