Asymmetrically and symmetrically coated tapered optical fiber for sensing applications
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
The deposition of a non-metallic thin-film in a symmetrically coated tapered optical fiber leads to the generation of resonances due to guidance of a mode in the thin-film. At certain conditions, the resonances overlap ...

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 ...
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 ...
Optimization of sensors based on multimode interference in single-mode–multimode– single-mode structure
(IEEE, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode
(SMS) structure with a complex refractive index thin-film the central
wavelength of the transmission and attenuation bands of the
optical spectrum can be shifted. By adequate ...
Recent developments in fiber optics humidity sensors
(MDPI, 2017)
Artículo / Artikulua,
A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical ...
