    • 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 ...
    • Overcoming non-local effects and Brillouin threshold limitations in Brillouin distributed sensors 

      Urricelqui Polvorinos, Javier Upna; Ruiz Lombera, Rubén; Sagüés García, Mikel Upna; Mirapeix, Jesús; López Higuera, José Miguel; Loayssa Lara, Alayn Upna (SPIE, 2015)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber and that ...
