    • Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings 

      Del Villar, Ignacio Upna; Achaerandio, Miguel Upna; Matías Maestro, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (Optical Society of America, 2005)   Artículo / Artikulua  OpenAccess
      It was proved that the deposition of an overlay material onto a long-period fiber grating causes important shifts in the wavelengths of the typical attenuation bands that are caused by coupling between cladding and core ...
    • Enhancement of sensitivity in long period fiber gratings with deposition of low refractive index materials 

      Del Villar, Ignacio Upna; Matías Maestro, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (Optical Society of America, 2005)   Artículo / Artikulua  OpenAccess
      It was proved [Opt. Lett. 30, 720 (2005)] that the deposition of an overlay of higher refractive index than that of the cladding on a long-period fiber grating (LPFG) causes large shifts in the attenuation bands induced by ...
    • Etched and nanocoated SMS fiber sensor for detection of salinity concentration 

      Cardona-Maya, Yamile; Del Villar, Ignacio Upna; Socorro Leránoz, Abián Bentor Upna; Corres Sanz, Jesús María Upna; Arregui San Martín, Francisco Javier Upna; Botero-Cadavid, Juan F. (MDPI, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • Influence in cladding mode distribution of overlay deposition on long-period fiber gratings 

      Del Villar, Ignacio Upna; Matías Maestro, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (Optical Society of America, 2006)   Artículo / Artikulua  OpenAccess
      A thin overlay of higher refractive index than that of the cladding of a long-period fiber grating induces in cladding modes strong variations in effective index, mode profile, cross-coupling coefficient with the core ...
    • Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors 

      Gallego, E.E.; Ascorbe Muruzabal, Joaquín Upna; Del Villar, Ignacio Upna; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna (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 ...
    • Wavelength and phase detection based SMS fiber sensors optimized with etching and nanodeposition 

      Cardona-Maya, Yamile; Del Villar, Ignacio Upna; Socorro Leránoz, Abián Bentor Upna; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna; Botero-Cadavid, Juan F. (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      The development of an optical fiber refractometer by hydrogen fluoride etching and sputtering deposition of a thin-film of indium tin oxide on a single-mode-multimode-single-mode fiber structure has been analyzed with ...
