• Design of optical fiber Bragg grating-based sensors for flow measurement in pipes 

      Diéguez Elizondo, Pedro Upna Orcid; Rodríguez Rodríguez, Armando; Urroz Unzueta, José Carlos Upna Orcid; López Rodríguez, José Javier Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (Taylor & Francis, 2023)   Artículo / Artikulua  OpenAccess
      In this work, optical Fiber Bragg grating (FBG) sensors were used to measure water flow in pipes. Several types of coatings were incorporated into the design of the sensors to examine their effects on the elastic strain ...
    • Optimization of fiber bragg gratings inscribed in thin films deposited on D-shaped optical fibers 

      Imas González, José Javier Upna Orcid; Ruiz Zamarreño, Carlos Upna Orcid; Del Villar, Ignacio Upna Orcid; Matías Maestro, Ignacio Upna Orcid (MDPI, 2021)   Artículo / Artikulua  OpenAccess
      A fiber Bragg grating patterned on a SnO2 thin film deposited on the flat surface of a D-shaped polished optical fiber is studied in this work. The fabrication parameters of this structure were optimized to achieve a ...
