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, ...
Bloch waves at the surface of a single-layer coating D-shaped photonic crystal fiber
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
Bloch surface wave (BSW) platforms are particularly interesting for light confinement and surface sensitivity, as an alternative to the metal-based surface plasmon polaritons (SPP). However, most of the reported BSW platforms ...
Lossy mode resonance optical sensors based on indium-gallium-zinc oxide thin film
(Elsevier, 2019)
Artículo / Artikulua,
This work discusses an application of electrically conductive and optically transparent indium-gallium-zinc oxide (IGZO) thin films for fabrication of lossy mode resonance (LMR) based optical fiber refractometers. The films ...
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
(Nature Research, 2019)
info:eu-repo/semantics/article,
The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ...
Fiber-based early diagnosis of venous thromboembolic disease by label-free D-dimer detection
(Elsevier, 2019)
info:eu-repo/semantics/article,
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 ...
Etched and nanocoated single-mode multimode single-mode (SMS) fibers for detection of wind turbine gearbox oil degradation
(IEEE, 2019)
info:eu-repo/semantics/article,
The application of an etching process in a single-mode multimode single-mode (SMS) fiber allows monitoring the change of refractive index of wind turbine gearbox oil due to temperature and degradation with a limitation at ...
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 ...
Advances in fiber optic DNA-based sensors: a review
(IEEE, 2021)
info:eu-repo/semantics/article,
DNA is becoming increasingly important in the domain of optical fiber sensors, either as a tool for biosensing, or as a target to detect. In this review the main contributions of the last years are presented both in the ...
High sensitivity lossy-mode resonance refractometer using low refractive index PFA planar waveguide
(Elsevier, 2023)
Artículo / Artikulua,
In this work a new strategy to improve the sensitivity of refractometers based on lossy-mode resonances has been proved. The proximity of the PFA (tetrafluoroethylene-perfluoro polymer) substrate refractive index to that ...
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 ...
