Tunable sensitivity in long period fiber gratings during mode transition with low refractive index intermediate layer
(IEEE, 2022)
Artículo / Artikulua,
Double-clad fibers where the second cladding has a lower refractive index than the first cladding, prove to be ideal structures for potentiating and tuning the sensitivity in long-period fiber gratings (LPFGs) operating ...
Wavelength and intensity based lossy mode resonance breathing sensor
(Elsevier, 2021)
info:eu-repo/semantics/article,
Copper oxide (CuO) allows the generation of lossy mode resonance (LMR) in a wide wavelength range of the optical spectrum, both in the visible and the near-infrared (NIR). For this, it is necessary to use a configuration ...
Ultrahigh sensitive detection of tau protein as Alzheimer's biomarker via microfluidics and nanofunctionalized optical fiber sensors
(Wiley, 2022)
Artículo / Artikulua,
Alzheimer’s disease (AD) is one of the most common neurodegenerative illnesses
displaying the highest death rate in the elderly. However, the existing AD
diagnostic system remains elusive due to lack of a technology that ...
Improving the width of lossy mode resonances in a reflection configuration D-shaped fiber by nanocoating laser ablation
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The full width at half maximum (FWHM) of lossy mode resonances (LMRs) in the optical spectrum depends on the homogeneity of the thin film deposited. In this Letter, a method for improving the FWHM is applied for an LMR ...
Bloch surface wave resonances generated with dielectric stack of high refractive index contrast deposited on a D-shaped optical fiber for sensing applications
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A 5-layer stack composed of TiO2 and Al2O3, two materials with a high refractive index contrast, was deposited on a D-shaped fiber to generate Bloch surface wave resonances with an improved figure of merit.
Alfalfa quality detection by means of VIS-NIR optical fiber reflection spectroscopy
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A first approach study for the classification of alfalfa (medicago sativa) quality has been performed by means of VIS-NIR optical fiber reflection spectroscopy. Reflection spectral data has been obtained from alfalfa samples ...
Trends in the design of intensity-based optical fiber biosensors (2010–2020)
(MDPI, 2021)
info:eu-repo/semantics/article,
There exists an increasing interest in monitoring low concentrations of biochemical species, as they allow the early-stage detection of illnesses or the monitoring of the environment quality. Thus, both companies and ...
Optimization of fiber Bragg gratings inscribed in thin films deposited on D-shaped optical fibers
(MDPI, 2021)
info:eu-repo/semantics/article,
A fiber Bragg grating patterned on a SnO2 thin film deposited on the flat surface of a D-shaped polished optical fiber is studied in this work. The fabrication parameters of this structure were optimized to achieve a ...
Micro sized interdigital capacitor for humidity detection based on agarose coating
(2021)
info:eu-repo/semantics/conferenceObject,
A micro sized interdigital capacitor has been proposed for the detection of relative humidity. The photolithography technique enables the fabrication of fingers with a size of 10x500 um. A thin film of agarose functionalizes ...
Generation of lossy mode resonances with different nanocoatings deposited on coverslips
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ...
