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 ...
Fringe generation with non-uniformly coated long-period fiber gratings
(Optical Society of America, 2007)
Artículo / Artikulua,
In this work, the spectral characteristics of non-uniform
symmetrically ring shaped coatings deposited on long-period fiber gratings
(LPFGs) have been theoretically and experimentally investigated. To
optimize the ...
Fiber optic multiple-wavelength filter based on one dimensional photonic bandgap structures with defects
(IEEE, 2004)
Artículo / Artikulua,
In this paper, a theoretical analysis is given of an
optical fiber multiple-wavelength tunable filter based on a onedimensional
(1-D) photonic bandgap (PBG) structure with four
defects. To understand the positioning of ...
Optimization of sensitivity in long period fiber gratings with overlay deposition
(Optical Society of America, 2005)
info:eu-repo/semantics/article,
The deposition of an overlay of higher refractive index than the
cladding in a Long Period Fiber Grating (LPFG) permits to improve the
sensitivity to ambient refractive index changes in a great manner. When the
overlay is ...
Analysis of one-dimensional photonic band gap structures with a liquid crystal defect towards development of fiber-optic tunable wavelength filters
(Optical Society of America, 2003)
info:eu-repo/semantics/article,
A theoretical analysis of a fiber optical photonic band gap based
tunable wavelength filter is presented. The design presented here is based on
the quarter wave reflector with a liquid crystal defect layer in the middle ...
Spectral evolution with incremental nanocoating of long period fiber gratings
(Optical Society of America, 2006)
Artículo / Artikulua,
The incremental deposition of a thin overlay on the cladding of a
long-period fiber grating (LPFG) induces important resonance wavelength
shifts in the transmission spectrum. The phenomenon is proved theoretically
with ...
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 ...
Strategies for fabrication of hydrogen peroxide sensors based on electrostatic self-assembly (ESA) method
(Elsevier, 2004)
Artículo / Artikulua,
An optical fiber sensor has been fabricated for detection of 5 M–0.1mM concentrations of hydrogen peroxide with a linear response. The
deposition method used is electrostatic self-assembly (ESA) of polymer cationic and ...
Nanodeposition of materials with complex refractive index in long period fiber gratings
(IEEE, 2005)
Artículo / Artikulua,
An overlay of higher refractive index than the
cladding is deposited on a Long Period Fiber Grating (LPFG).
This permits to improve in a great manner the sensitivity of the
device to ambient and overlay refractive index ...
ESA-based in-fiber nanocavity for hydrogen–peroxide detection
(IEEE, 2005)
Artículo / Artikulua,
A fiber-optic sensor sensitive to hydrogen peroxide
has been designed based on the electrostatic layer-by-layer selfassembly
method. Prussian blue has been deposited in a polymeric
structure formed by Poly(allylamine ...
