• Concrete beam bending test monitorization using a high strain fiber optic sensor 

      Bravo Acha, Mikel Upna Orcid; Sáenz, J.; Bravo Navas, M.; López-Amo Sáinz, Manuel Upna Orcid (IEEE / OSA, 2012)   Artículo / Artikulua  OpenAccess
      In this work the development of an 'eight-shape' fiber optic sensor for high strain measurement is experimentally demonstrated. This strain sensor is interrogated using a commercial optical time domain reflectometer through ...
    • Dual-wavelength single-longitudinal-mode erbium fiber laser for temperature measurements 

      Díaz Lucas, Silvia Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (SPIE, 2014)   Artículo / Artikulua  OpenAccess
      A dual-wavelength erbium fiber laser with single-longitudinal-mode characteristic is proposed and demonstrated. The system uses a 7-m-long highly doped erbium-doped fiber as the primary gain medium while two fiber Bragg ...
    • Low noise dual-wavelength erbium fiber laser in single-longitudinal-mode operation 

      Rota Rodrigo, Sergio Upna; Pérez Herrera, Rosa Ana Upna Orcid; Fernández Vallejo, Montserrat Upna; López-Amo Sáinz, Manuel Upna Orcid (Springer, 2012)   Artículo / Artikulua  OpenAccess
      A new stable dual-wavelength fiber-ring laser based on erbium-doped fiber amplification is reported. The laser is based on ring resonators and employs fiber Bragg gratings to select the operation wavelengths. The ...
