Generation of selective fringes with cascaded long-period gratings
(IEEE, 2006)
Artículo / Artikulua,
The inscription of cascaded long-period gratings of
different periods in optical fiber permits us to obtain both narrowband
and wideband filters in the same spectrum. If used as an
optical transducer, it may permit us ...
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
Generation of lossy mode resonances by deposition of high-refractive-index coatings on uncladded multimode optical fibers
(IOP Publishing Ltd, 2010)
Artículo / Artikulua,
A comparative study of lossy mode resonances generated by depositing two different materials
is presented. The two materials selected are indium tin oxide (ITO) and indium oxide. The two
materials present different ...
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
(Elsevier, 2018)
Artículo / Artikulua,
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
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 ...
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 ...
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 ...
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) ...
Fabrication of long period gratings by periodically removing the coating of cladding-etched single mode optical fiber towards optical fiber sensor development
(MDPI, 2018)
info:eu-repo/semantics/article,
Here, we present a novel method to fabricate long period gratings using standard single mode optical fibers (SMF). These optical devices were fabricated in a three-step process, which consisted of etching the SMF, then ...
