    • 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 ...
    • 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 ...
    • Synthesis of one dimensional electromagnetic bandgap structures with fully controlled parameters 

      Arnedo Gil, Israel Upna; Chudzik, Magdalena Upna; Percaz Ciriza, Jon Mikel Upna; Arregui Padilla, Iván Upna; Teberio Berdún, Fernando Upna; Benito Pertusa, David Upna; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna (IEEE, 2017)   Artículo / Artikulua  OpenAccess
      In this paper, we propose a novel synthesis strategy for the design of one dimensional electromagnetic bandgap (1- D-EBG) structures where all the performance parameters of these devices can fully be controlled, i.e., ...
