    • Optical fiber lasers assisted by microdrilled optical fiber tapers 

      Pérez Herrera, Rosa Ana Upna; Pallarés Aldeiturriaga, D.; Júdez Colorado, Aitor Upna; Rodríguez Cobo, L.; López-Amo Sáinz, Manuel Upna; López Higuera, José Miguel (Optical Society of America, 2019)   Artículo / Artikulua  OpenAccess
      In this Letter, we present an analysis of the backscattering generated in a microdrilled tapered fiber within a short-linear-cavity fiber laser. We propose and experimentally demonstrate a fiber cavity laser based on a ...
    • Virtual FBGs using saturable absorbers for sensing with fiber lasers 

      Rodríguez Cobo, L.; Pérez Herrera, Rosa Ana Upna; Quintela, M. A.; Ruiz Lombera, Rubén; López-Amo Sáinz, Manuel Upna; 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 ...
    • Wavelength converter using a highly Er-doped optical fiber ring laser 

      Pérez Herrera, Rosa Ana Upna; López-Amo Sáinz, Manuel Upna; Rodríguez, Luis; Ventura Rípodas, Daniel; López Higuera, José Miguel (IOP Publishing, 2018)   Artículo / Artikulua  OpenAccess
      This work presents an all-fiber wavelength converter based on a highly Er-doped fiber laser, which has been experimentally demonstrated. Frequencies from several kilohertz up to tens of gigahertz have been investigated. ...
