Etched and nanocoated SMS fiber sensor for detection of salinity concentration
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fibre refractometer has been developed by etching and deposition of a thin film of indium tin oxide (ITO) on a single-mode-multimode-single-mode (SMS) fibre structure. The interference between modes in this ...
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 ...
Optimization of sensors based on multimode interference in single-mode–multimode– single-mode structure
(IEEE, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode
(SMS) structure with a complex refractive index thin-film the central
wavelength of the transmission and attenuation bands of the
optical spectrum can be shifted. By adequate ...

(MDPI, 2017)
Artículo / Artikulua,
Luminescence-based sensing applications range from agriculture to biology, including
medicine and environmental care, which indicates the importance of this technique as a detection tool.
Luminescent optical sensors are ...
Optical fibre sensors using graphene-based materials: a review
(MDPI, 2017)
Artículo / Artikulua,
Graphene and its derivatives have become the most explored materials since Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The exceptional properties of graphene have attracted ...
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 ...
Optimization in nanocoated D-shaped optical fiber sensors
(Optical Society of America, 2017)
Artículo / Artikulua,
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here,
we show that the full width at half minimum (FWHM) of lossy mode resonance can be
reduced by optimizing the nanocoating width, thickness and ...
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
(Elsevier, 2018)
Artículo / Artikulua,
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
Generation of lossy mode resonances with absorbing thin-films
(IEEE, 2010)
Artículo / Artikulua,
The generation of lossy mode resonances with
absorbing thin-films is analyzed with electromagnetic theory. The
main differences with surface plasmon resonances are presented
and some rules are given towards an optimum ...
