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 ...
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 ...
Optical fiber lasers assisted by microdrilled optical fiber tapers
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
In this Letter, we present an analysis of the backscattering generated in a microdrilled tapered fiber within a short-linear-cavity fiber laser. We propose and experimentally demonstrate a fiber cavity laser based on a ...
Quasi-distributed vibration sensing using OFDR and weak reflectors
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
Sensitivity optimization of a microstructured optical fiber ammonia gas sensor by means of tuning the thickness of a metal oxide nano-coating
(IEEE, 2019)
Artículo / Artikulua,
In this paper, the influence of the thickness of
metallic-oxide coatings, ITO, and SnO2 on the sensitivity of a
microstructured optical fiber Fabry–Pérot (FP) has been studied
with the aim of developing ammonia gas fiber ...
Enhancement of the sensitivity of a volatile organic compounds MOF sensor by means of its structure
(MDPI, 2019)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...
