A comparative study between SMS interferometers and lossy mode resonace optical fiber devices for sensing applications
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
Optical fiber sensors are of great interest due to their intrinsic advantages over electronic sensors. In this work, the
sensing characteristics of two different and novel optical fiber devices are compared, after ...
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 ...
Optical fiber refractometers based on sputtered indium tin oxide coatings
(IEEE, 2011)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents the fabrication of optical fiber
refractometers based on indium tin oxide (ITO) coatings
deposited by sputtering with response in the visible spectral
region. ITO thin-films have been sputtered by ...
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ...
Title enhancement of the sensitivity of a volatile organic compounds MOF-sensor by means of its structure
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
Etched and nanocoated SMS fiber sensor for detection of salinity concentration
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fibre refractometer has been developed by etching and deposition of a thin film of indium tin oxide (ITO) on a single-mode-multimode-single-mode (SMS) fibre structure. The interference between modes in this ...
Monitoring the etching process in LPFGs towards development of highly sensitive sensors
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the monitoring of the etching process up to a diameter of 30 µm of two LPFG structures has been compared, one of them had initially 125 µm, whereas the second one had 80 µm. By tracking the wavelength shift ...
Optical fiber vacuum sensor based on modal interferometer and PDMS coating
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
This work studies the behavior of polydimethylsiloxane (PDMS) as a transducer for optical vacuum pressure measurements. The optical structure chosen for this device is a modal interferometer achieved by splicing a coreless ...
Relative humidity multi-point optical sensors system based on Fast Fourier multiplexing technique

In this paper, a new multipoint optical fiber system for relative humidity measurements based on Sn02-FP (Fabry-Pérot) sensing heads and an optical interrogator as single active device is presented and characterized. The ...
Fiber-optic lossy mode resonance sensors
(Elsevier, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
In the last 4 years, experimental evidences about the potential use of optical sensors based on Lossy Mode Resonances (LMR)
have been presented in the literature. These LMR sensors have some similarities with Surface ...
