Gas detection using LMR-based optical fiber sensors
(MDPI, 2018)
Artículo / Artikulua,
This work presents a first approach to the utilization of Lossy Mode Resonance (LMR)
based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film
fabricated onto the core of cladding ...
Liquid level sensor based on dynamic Fabry–Perot interferometers in processed capillary fiber
(Springer Nature, 2021)
info:eu-repo/semantics/article,
In this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive
index is designed, manufactured and demonstrated through simulations and experimentally. For
this, a silica capillary ...
Spatial-frequency multiplexing of high-sensitivity liquid level sensors based on multimode interference micro-fibers
(Elsevier, 2020)
info:eu-repo/semantics/article,
This paper shows a new fiber optic sensor multiplexed system for liquid level sensing. Biconical fibertapers converging at a 40 mm-long micro-fiber are used as transducers. The tapers are designed to providethe propagation ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
All fiber interferometer for ice detection
(Optica Publishing Group, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents an etched single-mode - multimode - single-mode structure that detects the solid-to-liquid change of state of the water due to an increased refractive index sensitivity within the 1.308 - 1.321 RIU range
Trends in the design of intensity-based optical fiber biosensors (2010–2020)
(MDPI, 2021)
info:eu-repo/semantics/article,
There exists an increasing interest in monitoring low concentrations of biochemical species, as they allow the early-stage detection of illnesses or the monitoring of the environment quality. Thus, both companies and ...
Simultaneous measurement of humidity and temperature based on a partially coated optical fiber long period grating
(Elsevier, 2016)
info:eu-repo/semantics/article,
A humidity and temperature optical fiber sensor based on a long-period grating (LPG), which can provide simultaneous response to both magnitudes, is proposed and demonstrated via experiments. Previously, the LPG was fully ...
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 ...
All-PM fiber loop mirror interferometer analysis and simultaneous measurement of temperature and mechanical vibration
(IEEE, 2018)
info:eu-repo/semantics/article,
In this work, a new all-polarization maintaining (PM) fiber loop mirror interferometer is proposed and validated as temperature and mechanical vibration sensor. The scheme employs the arms of a PM coupler as communication ...
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 ...
