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 ...
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 ...
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 ...
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. ...
