    • Influence of saturable absorbers on fiber ring laser sensors 

      Rodríguez Cobo, L.; Quintela, M. A.; Ruiz Lombera, Rubén; Pérez Herrera, Rosa Ana Upna; López-Amo Sáinz, Manuel Upna; López Higuera, José Miguel (SPIE, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a fiber ring laser sensor has been employed to analyze the influence of passive Er-doped fiber acting as saturable absorber. Lasing modes of fiber ring lasers can be reduced by properly locating a saturable ...
    • Optical fiber networks for remote fiber optic sensors 

      Fernández Vallejo, Montserrat Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2012)   Artículo / Artikulua  OpenAccess
      This paper presents an overview of optical fiber sensor networks for remote sensing. Firstly, the state of the art of remote fiber sensor systems has been considered. We have summarized the great evolution of these systems ...
    • Remote (250 km) fiber Bragg grating multiplexing system 

      Fernández Vallejo, Montserrat Upna; Rota Rodrigo, Sergio Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2011)   Artículo / Artikulua  OpenAccess
      We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ...
