A fiber optic ammonia sensor using a universal pH indicator
(MDPI, 2014)
Artículo / Artikulua,
A universal pH indicator is used to fabricate a fiber optic ammonia sensor. The advantage of this pH indicator is that it exhibits sensitivity to ammonia over a broad wavelength range. This provides a differential response, ...
Wavelength and phase detection based SMS fiber sensors optimized with etching and nanodeposition
(IEEE, 2016)
Artículo / Artikulua,
The development of an optical fiber refractometer by
hydrogen fluoride etching and sputtering deposition of a thin-film
of indium tin oxide on a single-mode-multimode-single-mode fiber
structure has been analyzed with ...
Generation of surface plasmon resonance and lossy mode resonance by thermal treatment of ITO thin-films
(Elsevier, 2014)
Artículo / Artikulua,
Silicon wafers coated with IndiumTinOxide (ITO) by application of sputtering technique have been
characterized after different post-annealing techniques, showing that this last factor is critical for the
quality of the ...
Mode transition in complex refractive index coated single-mode–multimode–single-mode structure
(Optical Society of America, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS)
structure with a high refractive index thin-film it is possible to obtain a
transition of modes for specific combinations of thin-film thickness, thinfilm
refractive ...
Gasohol quality control for real time applications by means of a multimode interference fiber sensor
(MDPI, 2014)
Artículo / Artikulua,
In this work we demonstrate efficient quality control of a variety of gasoline and ethanol (gasohol) blends using a multimode interference (MMI) fiber sensor. The operational principle relies on the fact that the addition ...
Development of a low mobility IEEE 802.15.4 compliant VANET system for urban environments
(MDPI, 2013)
Artículo / Artikulua,
The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information ...
Resonances in coated long period fiber gratings and cladding removed multimode optical fibers: a comparative study
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
Two optical fiber devices have been coated in parallel: a long
period fiber grating (LPFG) and a cladding-removed multimode optical
fiber (CRMOF). The progressive coating of the LPFG by means of the
layer-by-layer ...
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 ...
Design rules for lossy mode resonance based sensors
(Optical Society of America, 2012)
Artículo / Artikulua,
Lossy mode resonances can be obtained in the transmission spectrum of cladding removed
multimode optical fiber coated with a thin-film. The sensitivity of these devices to changes
in the properties of the coating or the ...
Refractometric sensors based on multimode interference in a thin-film coated singlemode– multimode–single-mode structure with reflection configuration
(Optical Society of America, 2014)
Artículo / Artikulua,
Thin-film coated single-mode–multimode–single-mode (SMS) structures have been analyzed both theoretically
and experimentally with the aim of detecting different refractive indices. By adequate selection
of the thickness ...
