Is there a frontier in sensitivity with lossy mode resonance (LMR) based refractometers?
(Nature Publishing Group, 2017)
Artículo / Artikulua,
A tin dioxide thin layer has been studied in order to improve the sensitivity of lossy mode resonances (LMR) based sensors. The effects of the thin film thickness and the polarization of light in a SnO2 coated D-shaped ...
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 ...
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 ...

Desde su desarrollo en los años 60 hasta nuestros días, los láseres de fibra óptica
han ido incrementando su importancia en diversos ámbitos de nuestra vida. Ya sea
en la medicina, la electrónica de consumo o la industria, ...
Electromagnetic response of extraordinary transmission plates inspired on Babinet’s principle
(InTech, 2011)
Capítulo de libro / Liburuen kapitulua,
This chapter is devoted to polarization effects arisen from perforated metallic plates
exhibiting extraordinary transmission (ET). Setting aside the state-of-the-art of perforated
metallic plates, we show that by applying ...
Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
(Hindawi Publishing Corporation, 2010)
Artículo / Artikulua,
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter
measurements and planar near-field scanning of the radiated field. A multifrequency array with ...
ASTRA 3B horn antenna design
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
The ASTRA 3B satellite includes 60 Ku-band state-of-the-
art transponders and 4 Ka-band transponders. The
spacecraft have been designed for the distribution of
both direct-to-home (DTH) broadcast services and two way
broadband ...
