AC/DC millivoltage sensor by means of ITO-coated optical fibers: towards monitoring of biosignals
Aginaga Etxamendi, Concepción Isabel; Socorro Leránoz, Abián Bentor
; Fuentes Lorenzo, Omar; Del Villar, Ignacio ; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (IEEE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
This contribution shows the monitoring of AC and DC millivoltage signals by means of lossy mode resonances generated by Indium Tin Oxide (ITO) on optical fibers. Sensors were obtained by sputtering ITO thin-films onto 25 ... -

Generation of lossy mode resonances in planar waveguides toward development of humidity sensors
Fuentes Lorenzo, Omar; Corres Sanz, Jesús María; Matías Maestro, Ignacio ; Del Villar, Ignacio (IEEE, 2019)
Artículo / Artikulua
Lossy mode resonances (LMRs) are typically obtained with optical fibre. The Kretschmann configuration is an alternative but LMRs are generated with angles approaching grazing incidence. In this work, a new setup is explored, ... -
Generation of lossy mode resonances with different nanocoatings deposited on coverslips
Fuentes Lorenzo, Omar; Goicoechea Fernández, Javier; Corres Sanz, Jesús María ; Del Villar, Ignacio ; Ozcariz Celaya, Aritz ; Matías Maestro, Ignacio (Optical Society of America, 2020)
Artículo / Artikulua
The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ... -
Increasing the sensitivity of an optic level sensor with a wavelength and phase sensitive single-mode multimode single-mode (SMS) fiber structure
Fuentes Lorenzo, Omar; Del Villar, Ignacio; Vento, José R.; Socorro Leránoz, Abián Bentor ; Gallego, E.E.; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (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 ... -
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
Fuentes Lorenzo, Omar; Del Villar, Ignacio; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (Nature Research, 2019)
Artículo / Artikulua
The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ... -
Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
Del Villar, Ignacio; Fuentes Lorenzo, Omar; Chiavaioli, Francesco; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (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 ... -
Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction
Del Villar, Ignacio; Partridge, Matthew; Rodríguez, Wenceslao; Fuentes Lorenzo, Omar; Socorro Leránoz, Abián Bentor ; Díaz Lucas, Silvia ; Corres Sanz, Jesús María ; James, Stephen; Tatam, Ralph (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 ...
