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 ...
Interferometric vs wavelength selective optical fiber sensors for cryogenic temperature measurements
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this work, a preliminary study of the behavior of two different interferometric fiber optic sensors and two different wavelength selective fiber optic sensors is performed. A photonic cristal fiber Fabry-Pérot interferometer, ...
Polyaniline deposition on tilted fiber Bragg grating for pH sensing
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, we present the results of a new pH sensor based on a polyaniline (PAni) coating on the surface of a tilted fiber Bragg grating. The pH-sensitive PAni was deposited by in situ chemical oxidative polymerization. ...
Sensitivity enhancement by diameter reduction in low cutoff wavelength single-mode multimode singlemode (SMS) fiber sensors
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
Two different low cutoff wavelength single-mode fibers were used in single-mode multimode single-mode (SMS) configuration with the aim of designing sensors operating at short wavelengths, where optical sources and spectrometers ...
Sources of noise in Brillouin optical time-domain analyzers
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents a thorough study of the different sources of noise affecting Brillouin optical time-domain analyzers (BOTDA), providing a deep insight into the understanding of the fundamental limitations of this kind ...
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ...
