    • 46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors 

      Fernández Vallejo, Montserrat Upna; Olier Aguado, David; Zornoza Indart, Ander; Pérez Herrera, Rosa Ana Upna; Díaz Lucas, Silvia Upna; Elosúa Aguado, César Upna; Bariáin Aisa, Cándido Upna; Loayssa Lara, Alayn Upna; López-Amo Sáinz, Manuel Upna (IEEE, 2012)   Artículo / Artikulua  OpenAccess
      We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ...
    • 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 ...
    • L-band multiwavelength single-longitudinal mode fiber laser for sensing applications 

      Pérez Herrera, Rosa Ana Upna; Ullán Nieto, Ángel; Leandro González, Daniel Upna; Fernández Vallejo, Montserrat Upna; Quintela, M. A.; Loayssa Lara, Alayn Upna; López Higuera, José Miguel; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2012)   Artículo / Artikulua  OpenAccess
      In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in the L-band is proposed and experimentally demonstrated. The sensor system presented here is based on ring ...
    • Stability comparison of two ring resonator structures for multiwavelength fiber lasers using highly doped Er-fibers 

      Pérez Herrera, Rosa Ana Upna; Quintela, M. A.; Fernández Vallejo, Montserrat Upna; Quintela, Antonio; López-Amo Sáinz, Manuel Upna; López Higuera, José Miguel (IEEE / OSA, 2009)   Artículo / Artikulua  OpenAccess
      An experimental comparison of stability between two different fiber laser topologies is carried out. The lasers are based on ring resonators that include highly-doped Er-fibers. Both topologies use fiber Bragg grating ...
    • Stable multi-wavelength erbium fiber ring laser with optical feedback for remote sensing 

      Díaz Lucas, Silvia Upna; Leandro González, Daniel Upna; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2015)   Artículo / Artikulua  OpenAccess
      In this work, we demonstrate a stable fiber sensing system for remote temperature measurements, where the sensing element is an array of four fiber Bragg gratings (FBGs) and sensor interrogation is achieved with a ...
