Deposition of coatings on long-period fiber gratings: tunnel effect analogy
(Springer, 2006)
Artículo / Artikulua,
The sensitivity of Long-period fiber gratings (LPFGs), coated with high-refractive-index thin
film overlays, to the refractive index and the thickness of the overlay, and to the ambient refractive
index, can be enhanced ...
Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings
(Optical Society of America, 2005)
Artículo / Artikulua,
It was proved that the deposition of an overlay material onto a long-period fiber grating causes important
shifts in the wavelengths of the typical attenuation bands that are caused by coupling between cladding and
core ...
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 ...
Monitoring of water freeze-thaw cycle by means of an etched single-mode - multimode - single-mode fiber-optic refractometer
(IEEE, 2023)
Artículo / Artikulua,
As an alternative to the different technologies that permit the detection of in-situ ice formation on different surfaces, this contribution proposes the design of an etched single-mode – multimode – single-mode (E-SMS) ...
A comparative study between SMS interferometers and lossy mode resonace optical fiber devices for sensing applications
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
Optical fiber sensors are of great interest due to their intrinsic advantages over electronic sensors. In this work, the
sensing characteristics of two different and novel optical fiber devices are compared, after ...
All fiber interferometer for ice detection
(Optica Publishing Group, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents an etched single-mode - multimode - single-mode structure that detects the solid-to-liquid change of state of the water due to an increased refractive index sensitivity within the 1.308 - 1.321 RIU range
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 ...
An optimized method based on digitalized Lissajous curve to determine lifetime of luminescent materials on optical fiber sensors
(Hindawi, 2016)
Artículo / Artikulua,
A method is proposed to determine lifetime of luminescent emissions based on the phase shift measurement employing the digitalized Lissajous representation: this diagram has been typically used with analogical algorithms, ...
Multichannel refractometer based on lossy mode resonances
(IEEE, 2022)
info:eu-repo/semantics/article,
In this work a new multiparameter sensor platform based on lossy mode resonances is presented. The structure consists of a soda-lime optical slab waveguide butt-coupled to multimode optical fibers. A variable thickness ...
A comparative study in the sensitivity of optical fiber refractometers based on the incorporation of gold nanoparticles into layer-by-layer films
(Exeley, 2015)
info:eu-repo/semantics/article,
In this work, optical fiber refractometers based on the successive incorporation of gold nanoparticles have been fabricated by means of the Layer-by-Layer Embedding (LbL-E) deposition technique. This enables the apparition ...
