    • Compound lasing fiber optic ring resonators for sensor sensitivity enhancement 

      Rota Rodrigo, Sergio Upna; González Herráez, Miguel; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2015)   Artículo / Artikulua  OpenAccess
      In this work, a new method for increasing simultaneously the sensitivity and interrogation stability of fiberoptic intensity sensors is presented. The configuration is based on a double-coupler ring resonator. On one side, ...
    • Frequency modulated continuous wave system for optical fiber intensity sensors with optical amplification 

      Pérez Herrera, Rosa Ana Upna; Frazão, Orlando; Santos, José Luís; Araújo, Francisco Moita; Ferreira, Luis Alberto; Baptista, José Manuel; López-Amo Sáinz, Manuel Upna (IEEE, 2009)   Artículo / Artikulua  OpenAccess
      We report on the use of erbium doped fiber (EDF) amplification to enhance a frequency modulated continuous wave (FMCW) technique for referencing optical intensity sensors located between two Bragg grating structures. The ...
