Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction
(MDPI, 2017)
Artículo / Artikulua,
The diameter of long-period fiber gratings (LPFGs) fabricated in optical fibers with a low cutoff wavelength was be reduced by hydrofluoric acid etching, enhancing the sensitivity to refractive index by more than a factor ...
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 ...
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 ...
Arc-induced long period fiber gratings in the dispersion turning points
(IEEEOptical Society of America, 2016)
Artículo / Artikulua,
We demonstrated the possibility to inscribe longperiod
fiber gratings (LPFGs) in a B/Ge codoped fiber by using
grating periods shorter than 150 μm. We also have arc-induced
in the SMF 28 fiber an LPFG in the dispersion ...
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 ...
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 ...
Experimental demonstration of lossy mode and surface plasmon resonance generation with Kretschmann configuration
(Optical Society of America, 2015)
Artículo / Artikulua,
Lossy mode resonances (LMRs) and surface plasmon resonaces
(SPRs) are obtained experimentally with a Kretschmann
configuration using a BK7 glass prism with all sides polished
and coated with indium tin oxide (ITO). The ...
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 ...
