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 ...
Optical fiber refractometers based on indium tin oxide coatings with response in the visible spectral region
(Elsevier, 2011)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents the fabrication of optical fiber refractometers based on indium tin oxide (ITO) coatings with
response in the visible spectral region. ITO thin-films have been sputtered by employing a rotating mechanism ...
Tunable electro-optic wavelength filter based on lossy-guided mode resonances
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
In this work an optical fiber tunable filter based on lossy guided-mode resonances (LGMR) is proposed. It consists of a multilayer structure deposited onto the surface of a plastic cladding removed multimode fiber. The ...
High sensitive refractometers based on lossy mode resonances (LMRs) supported by ITO coated D-shaped optical fibers
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
Tin doped indium oxide (ITO) coatings fabricated onto D-shaped
optical fibers are presented as the supporting medium for Lossy Mode
Resonances (LMRs) generation. The characteristic geometry of ITO-coated
D-shaped optical ...
Recent developments in fiber optics humidity sensors
(MDPI, 2017)
Artículo / Artikulua,
A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical ...
Humidity sensor based on Bragg gratings developed on the end facet of an optical fiber by sputtering of one single material
(MDPI, 2017)
Artículo / Artikulua,
The refractive index of sputtered indium oxide nanocoatings has been altered just by changing the sputtering parameters, such as pressure. These induced changes have been exploited for the generation of a grating on the ...
A fiber optic ammonia sensor using a universal pH indicator
(MDPI, 2014)
Artículo / Artikulua,
A universal pH indicator is used to fabricate a fiber optic ammonia sensor. The advantage of this pH indicator is that it exhibits sensitivity to ammonia over a broad wavelength range. This provides a differential response, ...
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 ...
Monitoring the etching process in LPFGs towards development of highly sensitive sensors
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the monitoring of the etching process up to a diameter of 30 µm of two LPFG structures has been compared, one of them had initially 125 µm, whereas the second one had 80 µm. By tracking the wavelength shift ...
Generation of lossy mode resonances by deposition of high-refractive-index coatings on uncladded multimode optical fibers
(IOP Publishing Ltd, 2010)
Artículo / Artikulua,
A comparative study of lossy mode resonances generated by depositing two different materials
is presented. The two materials selected are indium tin oxide (ITO) and indium oxide. The two
materials present different ...
