    • Aluminum doped zinc oxide (AZO) coated optical fiber LMR refractometers—An experimental demonstration 

      Ozcariz Celaya, Aritz Upna; Piña-Azamar, Dafne A.; Ruiz Zamarreño, Carlos Upna; Dominguez, René; Arregui San Martín, Francisco Javier Upna (Elsevier, 2019)   Artículo / Artikulua
      This work presents the experimental demonstration of lossy mode resonance generation by means of aluminum doped zinc oxide thin-films. The use of such material may allow to optimize the performance of LMR-based sensors, ...
    • Fluorescent sensors for the detection of heavy metal ions in aqueous media 

      Acha Morrás, Nerea de Upna; Elosúa Aguado, César Upna; Corres Sanz, Jesús María Upna; Arregui San Martín, Francisco Javier Upna (MDPI, 2019)   Artículo / Artikulua  OpenAccess
      Due to the risks that water contamination implies for human health and environmental protection, monitoring the quality of water is a major concern of the present era. Therefore, in recent years several efforts have been ...
    • Layer-by-layer nano-assembly: a powerful tool for optical fiber sensing applications 

      Rivero Fuente, Pedro J. Upna; Goicoechea Fernández, Javier Upna; Arregui San Martín, Francisco Javier Upna (MDPI, 2019)   Artículo / Artikulua  OpenAccess
      The ability to tune the composition of nanostructured thin films is a hot topic for the design of functional coatings with advanced properties for sensing applications. The control of the structure at the nanoscale level ...
    • Lossy mode resonance optical sensors based on indium-gallium-zinc oxide thin film 

      Ozcariz Celaya, Aritz Upna; Dominik, Magdalena; Smietana, Mateusz; Ruiz Zamarreño, Carlos Upna; Del Villar, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (Elsevier, 2019)   Artículo / Artikulua
      This work discusses an application of electrically conductive and optically transparent indium-gallium-zinc oxide (IGZO) thin films for fabrication of lossy mode resonance (LMR) based optical fiber refractometers. The films ...
    • Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors 

      López Aldaba, Aitor Upna; López Torres, Diego Upna; Elosúa Aguado, César Upna; Arregui San Martín, Francisco Javier Upna; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel Upna (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ...
