Temperature sensor based on a hybrid ITOsilica resonant cavity
(Optical Society of America, 2015)
Artículo / Artikulua,
Integrated optical devices comprised of multiple material systems are able to achieve unique performance characteristics, enabling applications in sensing and in telecommunications. Due to ease of fabrication, the majority ...
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 ...
Vibration detection using optical fiber sensors
(Hindawi, 2010)
info:eu-repo/semantics/article,
Condition monitoring of heavy electromechanical equipment is commonly accomplished in the industry using vibration analysis.
Several techniques, mainly based on capacitive and piezoelectric accelerometers, have been applied ...
Fabrication of Bragg gratings on the end facet of standard optical fibers by sputtering the same material
(IEEE, 2016)
Artículo / Artikulua,
A sputtering process has been applied to deposit quarter-wavelength stacks on the end facet of cleaved optical fibers by using only one sputtering target. Standard multimode optical fibers were used as substrates to fabricate ...
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 ...
Etched LPFGs in reflective configuration for sensitivity and attenuation band depth increase
(IEEE, 2016)
Artículo / Artikulua,
A reflection configuration setup for long-period
fiber gratings is presented. It permits to obtain a unique band
with attenuation double than that obtained in transmission
configuration, which is interesting for ...
Sensitivity optimization with cladding-etched long period fiber gratings at the dispersion turning point
(Optical Society of America, 2016)
Artículo / Artikulua,
This work presents a refractive index sensor based on a long period fiber grating
(LPFG) made in a reduced cladding fiber whose low order cladding modes have the turning
point at large wavelengths. The combination of ...
Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod

to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
Increasing the sensitivity of an optic level sensor with a wavelength and phase sensitive single-mode multimode single-mode (SMS) fiber structure
(IEEE, 2017)
Artículo / Artikulua,
The sensitivity of a liquid level sensor based on
a single-mode-multimode-single-mode fiber structure has been
increased by hydrofluoric acid etching. The etching process was
analyzed and monitored both theoretical and ...
