Mode transitions and thickness measurements during deposition of nanoscale TiO2 coatings on tilted fiber Bragg gratings
(IEEE, 2022)
Artículo / Artikulua,
The mode transition is a phenomenon observed in
thin film coated long period fiber gratings (LPGs) and singlemode multimode single-mode (SMS) fibers for certain values of
the coating thickness and refractive index, ...
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 ...
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 ...
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 ...
Spectral measurements with hybrid LMR and SAW platform for dual parameter sensing
(Royal Society of Chemistry, 2022)
Artículo / Artikulua,
Lossy mode resonance (LMR)-based optical sensors change their wavelength upon contact with substances or gases. This allows developing applications to detect the refractive index of the surrounding medium and even the ...
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 ...
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.
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
(SPIE, 2020)
info:eu-repo/semantics/conferenceObject,
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
Generation of lossy mode resonances in a broadband range with multilayer coated coverslips optimized for humidity sensing
(Elsevier, 2020)
info:eu-repo/semantics/article,
Coverslips deposited with a metallic oxide can be employed for generating lossy mode resonances by lateral incidence of light on the coverslip. Here it is demonstrated that with copper oxide the fading observed with other ...
Optical fiber vacuum sensor based on etched SMS structure and PDMS coating
(IEEE, 2020)
info:eu-repo/semantics/article,
In this work, an optical fiber vacuum sensor based on a single-mode multimode single-mode (SMS) structure coated with polydimethylsiloxane (PDMS) is studied. The SMS structure generates an interferometric pattern based on ...
