Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
Development of an in-fiber nanocavity towards detection of volatile organic gases
(MDPI, 2006)
Artículo / Artikulua,
A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has been developed and characterized for some organic gasses. The sensor is based on a novel vapochromic material, which is able to change its optical ...
Pyridine vapors detection by an optical fibre sensor
(MDPI, 2008)
Artículo / Artikulua,
An optical fibre sensor has been implemented towards pyridine vapors detection; to achieve this, a novel vapochromic material has been used, which, in solid state, suffers a change in colour from blue to pink-white in ...
Sensitivity improvement of a humidity sensor based on silica nanospheres on a long-period fiber grating
(MDPI, 2009)
Artículo / Artikulua,
This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO(2)-nanospheres film. An intermediate higher refractive index overlay, ...
Application of gold complexes in the development of sensors for volatile organic compounds
(World Gold Council, 2007)
Artículo / Artikulua,
Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
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 ...
Influence in cladding mode distribution of overlay deposition on long-period fiber gratings
(Optical Society of America, 2006)
Artículo / Artikulua,
A thin overlay of higher refractive index than that of the cladding of a long-period fiber grating induces in
cladding modes strong variations in effective index, mode profile, cross-coupling coefficient with the core ...
Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings
(Optical Society of America, 2005)
Artículo / Artikulua,
It was proved that the deposition of an overlay material onto a long-period fiber grating causes important
shifts in the wavelengths of the typical attenuation bands that are caused by coupling between cladding and
core ...
Long period fiber gratings with overlay of variable refractive index
(IEEE, 2005)
Artículo / Artikulua,
A theoretical analysis is presented of a long-period
fiber grating (LPFG) with an overlay of variable refractive index.
The highest sensitivity of the resonance wavelengths to variations
in the refractive index of the ...
Enhancement of sensitivity in long period fiber gratings with deposition of low refractive index materials
(Optical Society of America, 2005)
Artículo / Artikulua,
It was proved [Opt. Lett. 30, 720 (2005)] that the deposition of an overlay of higher refractive index than
that of the cladding on a long-period fiber grating (LPFG) causes large shifts in the attenuation bands induced
by ...
