Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod
fiber gratings are combined toward an increase of the sensitivity
to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
Optimization in nanocoated D-shaped optical fiber sensors
(Optical Society of America, 2017)
Artículo / Artikulua,
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here,
we show that the full width at half minimum (FWHM) of lossy mode resonance can be
reduced by optimizing the nanocoating width, thickness and ...
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 ...
Increasing the sensitivity of an optic level sensor with a wavelength and phase sensitive single-mode multimode single-mode (SMS) fiber structure
(IEEE, 2017)
Artículo / Artikulua,
The sensitivity of a liquid level sensor based on
a single-mode-multimode-single-mode fiber structure has been
increased by hydrofluoric acid etching. The etching process was
analyzed and monitored both theoretical and ...
Giant sensitivity of optical fiber sensors by means of lossy moderesonance
(Elsevier, 2016)
Artículo / Artikulua,
Here we show an optical refractometer with a giant sensitivity of 304,360 nm per refractive index unit(nm/RIU). This sensitivity corresponds to a resolution of 3.28 × 10−9RIU if a standard optical spectrumanalyzer with a ...
Etched LPFGs in reflective configuration for sensitivity and attenuation band depth increase
(IEEE, 2016)
Artículo / Artikulua,
A reflection configuration setup for long-period
fiber gratings is presented. It permits to obtain a unique band
with attenuation double than that obtained in transmission
configuration, which is interesting for ...
Generation of lossy mode resonances with absorbing thin-films
(IEEE, 2010)
Artículo / Artikulua,
The generation of lossy mode resonances with
absorbing thin-films is analyzed with electromagnetic theory. The
main differences with surface plasmon resonances are presented
and some rules are given towards an optimum ...
Sensors based on thin-film coated cladding removed multimode optical fiber and single-mode multimode single-mode fiber: a comparative study
(Hindawi Publishing Corporation, 2015)
Artículo / Artikulua,
Two simple optical fibre structures that do not require the inscription of a grating, a cladding removed multimode optical fibre
(CRMOF) and a single-mode multimode single-mode structure (SMS), are compared in terms of ...
Sensitivity optimization with cladding-etched long period fiber gratings at the dispersion turning point
(Optical Society of America, 2016)
Artículo / Artikulua,
This work presents a refractive index sensor based on a long period fiber grating
(LPFG) made in a reduced cladding fiber whose low order cladding modes have the turning
point at large wavelengths. The combination of ...
An analysis matrix for the assessment of smart city technologies: main results of its application
(MDPI, 2017)
Artículo / Artikulua,
The paper presents the main results of a previously developed methodology to better evaluate new technologies in Smart Cities, using a tool to evaluate different systems and technologies regarding their usefulness, considering ...
