    • An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber 

      Rota Rodrigo, Sergio Upna; Rodrigues Pinto, Ana Margarida Upna; Bravo Acha, Mikel Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2013)   Artículo / Artikulua  OpenAccess
      A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of ...
    • Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point 

      Del Villar, Ignacio Upna; Fuentes, Omar; Chiavaioli, Francesco; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      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 ...
