Refractometric sensors based on multimode interference in a thin-film coated singlemode– multimode–single-mode structure with reflection configuration
(Optical Society of America, 2014)
Artículo / Artikulua,
Thin-film coated single-mode–multimode–single-mode (SMS) structures have been analyzed both theoretically
and experimentally with the aim of detecting different refractive indices. By adequate selection
of the thickness ...
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 ...
Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction
(MDPI, 2017)
Artículo / Artikulua,
The diameter of long-period fiber gratings (LPFGs) fabricated in optical fibers with a low cutoff wavelength was be reduced by hydrofluoric acid etching, enhancing the sensitivity to refractive index by more than a factor ...
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
fiber gratings are combined toward an increase of the sensitivity
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 ...
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 ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
