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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
Lossy mode resonance generation with indium tin oxide coated optical fibers for sensing applications
(IEEE, 2010)
Artículo / Artikulua,
Surface plasmon resonances and lossy mode
resonances can be generated with Indium Tin Oxide (ITO)
coated optical fibers. Both phenomena are analyzed and
compared. Lossy mode resonances present important
advantages: ...
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 ...
