    • 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 Orcid; 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. ...
    • Modulated fiber ring laser and its application in high-sensitivity temperature sensors 

      Pérez Herrera, Rosa Ana Upna Orcid; Tainta Ausejo, Santiago Upna Orcid; Erro Betrán, María José Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (SPIE, 2016)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      This work presents an experimental demonstration of a scheme based on an internally modulated fiber ring laser for high-sensitivity temperature sensing. The attained temperature resolution has been as low as ± 2pm even ...
    • Virtual FBGs using saturable absorbers for sensing with fiber lasers 

      Rodríguez Cobo, L.; Pérez Herrera, Rosa Ana Upna Orcid; Quintela, M. A.; Ruiz Lombera, Rubén; López-Amo Sáinz, Manuel Upna Orcid; López Higuera, José Miguel (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
