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 ...
High sensitive refractometers based on lossy mode resonances (LMRs) supported by ITO coated D-shaped optical fibers
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
Tin doped indium oxide (ITO) coatings fabricated onto D-shaped
optical fibers are presented as the supporting medium for Lossy Mode
Resonances (LMRs) generation. The characteristic geometry of ITO-coated
D-shaped optical ...
Micro and nanostructured materials for the development of optical fibre sensors
(MDPI, 2017)
info:eu-repo/semantics/article,
The measurement of chemical and biomedical parameters can take advantage of the features
exclusively offered by optical fibre: passive nature, electromagnetic immunity and chemical stability
are some of the most relevant ...
Spectral measurements with hybrid LMR and SAW platform for dual parameter sensing
(Royal Society of Chemistry, 2022)
Artículo / Artikulua,
Lossy mode resonance (LMR)-based optical sensors change their wavelength upon contact with substances or gases. This allows developing applications to detect the refractive index of the surrounding medium and even the ...
Femtomolar detection by nanocoated fiber label-free biosensors
(ACS, 2018)
Artículo / Artikulua,
The advent of optical fibre-based biosensors combined with that of nanotechnologies has provided an oppor-tunity for developing in situ, portable, lightweight, versatile and high-performance optical sensing platforms. We ...
Improving the width of lossy mode resonances (LMRs) in double-clad fibers
(IEEE, 2023)
Artículo / Artikulua,
In this work, the characteristics of lossy mode resonances (LMRs) in double-clad fibers where the refractive index (RI) of the second cladding is lower than that of the first cladding are analyzed both numerically and ...
Surface exciton polariton resonances (SEPR)-based sensors
(Elsevier, 2023)
Artículo / Artikulua,
A new type of resonance in the development of sensors using long-range surface exciton polariton (LRSEP) phenomena has been coined: surface exciton plasmon resonance (SEPR). The resonance was obtained in the reflected ...
