Compact optical fiber lasers and optical fiber sensors assisted by femtosecond laser inscription of plane-by-plane FBGs
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Development of a high temperature sensor based on optical fiber l aser generated from a cavity of reduced dimensions (43 mm) in Er-doped fiber. The mirror FBGs have been inscribed with femtosecond laser using the slit beam ...
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 ...
WDM and TDM interrogation by sequentially pulsing direct modulated DFBs
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
A new versatile and cost-effective interrogation system by pulsing direct modulated (DM) DFB laser diodes is proposed. 1 pm wavelength resolution and 600 m sensor spacing is demonstrated by sequentially pulsing a DM DFB.
Multicore fiber sensors for strain measurement towards traffic monitoring
(SPIE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, two new interferometric sensors based on multicore optical fibers for the measurement of strain with the
ultimate goal of traffic monitoring are presented. The operating principle of each sensor relied on ...
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-drilled optical fiber for enhanced laser strain sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical
fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ...
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ...
