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 ...
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, ...
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, ...
A user-centric privacy framework for pervasive environments
(Springer, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
One inherent feature of pervasive computing environments is the need
to gather and process context information about real persons. Unfortunately, this
unavoidably affects persons¿ privacy to a large degree. Each time ...
Development of an optical refractometer by analysis of one-dimensional photonic bandgap structures with defects
(Optical Society of America, 2003)
Artículo / Artikulua,
A theoretical analysis of an optical fiber photonic-bandgap-based refractometer is presented. The design is based on a quarter-wave ref lector with one defect. By modifying both the real and the imaginary parts of the index ...
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 ...
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 ...
