      Del Villar, Ignacio Upna; Cruz, José Luis; Socorro Leránoz, Abián Bentor Upna; Díaz Lucas, Silvia Upna; Corres Sanz, Jesús María Upna; Arregui San Martín, Francisco Javier Upna; Matías Maestro, Ignacio Upna (MDPI, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • SnO2-MOF-Fabry-Pérot humidity optical sensor system based on Fast Fourier transform technique 

      López Aldaba, Aitor Upna; López Torres, Diego Upna; Ascorbe Muruzabal, Joaquín Upna; Rota Rodrigo, Sergio Upna; Elosúa Aguado, César Upna; López-Amo Sáinz, Manuel Upna; Arregui San Martín, Francisco Javier Upna; Corres Sanz, Jesús María Upna; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe (SPIE, 2016)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper, a new sensor system for relative humidity measurements based on a SnO2 sputtering deposition on a microstructured optical fiber (MOF) low-finesse Fabry-Pérot (FP) sensing head is presented and characterized. ...
