    • All-fiber lasers through photonic crystal fibers 

      Rodrigues Pinto, Ana Margarida Upna; López-Amo Sáinz, Manuel Upna (Science Wise Publishing & De Gruyter, 2013)   Artículo / Artikulua  OpenAccess
      A review on all-fiber lasers based on photonic crystal fibers is presented. Photonic crystal fibers present improved features beyond what conventional optical fibers can offer. Due to their geometric versatility, photonic ...

    • Comparison between capacitive and microstructured optical fiber soil moisture sensors 

      López Aldaba, Aitor Upna; López Torres, Diego Upna; Campo-Bescós, Miguel Upna; López Rodríguez, José Javier Upna; Yerro Lizarazu, David; Elosúa Aguado, César Upna; Arregui San Martín, Francisco Javier Upna; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel Upna (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ...

    • Experimental and numerical characterization of a hybrid Fabry-Perot cavity for temperature sensing 

      López Aldaba, Aitor Upna; Rodrigues Pinto, Ana Margarida Upna; López-Amo Sáinz, Manuel Upna; Frazão, Orlando; Santos, José Luís; Baptista, José Manuel; Baierl, Hardy; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe (MDPI, 2015)   Artículo / Artikulua  OpenAccess
      A hybrid Fabry-Pérot cavity sensing head based on a four-bridge microstructured fiber is characterized for temperature sensing. The characterization of this cavity is performed numerically and experimentally in the L-band. ...

    • 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 ...

    • Recent developments in fiber optics humidity sensors 

      Ascorbe Muruzabal, Joaquín Upna; Corres Sanz, Jesús María Upna; Arregui San Martín, Francisco Javier Upna; Matías Maestro, Ignacio Upna (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical ...

    • SnO2-MOF-Fabry-Perot optical sensor for relative humidity measurements 

      López Aldaba, Aitor Upna; López Torres, Diego Upna; Elosúa Aguado, César Upna; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; Arregui San Martín, Francisco Javier Upna; López-Amo Sáinz, Manuel Upna (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, a new optical fiber sensor for relative humidity measurements is presented and characterized. The sensor is based on a SnO2 sputtering deposition on a microstructured optical fiber (MOF) low-finesse Fabry-Pérot ...
