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 ...
Luminescence-based optical sensors fabricated by means of the layer-by-layer nano-assembly technique
(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 ...
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 ...
Title enhancement of the sensitivity of a volatile organic compounds MOF-sensor by means of its structure
(MDPI, 2017)
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. ...
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 ...
