    • 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 Orcid; Díaz Lucas, Silvia Upna Orcid; Elosúa Aguado, César Upna Orcid; Bariáin Aisa, Cándido Upna Orcid; Loayssa Lara, Alayn Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (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 ...

    • Comparison of wavelength-division-multiplexed distributed fiber Raman amplifier networks for sensors 

      Díaz Lucas, Silvia Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (Optical Society of America, 2006)   Artículo / Artikulua  OpenAccess
      A novel distributed fiber Raman amplified star topology used for optical sensor wavelength-division multiplexing is proposed. The performance of this star configuration is compared to an optically amplified bus topology. ...

    • 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 ...

    • Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification 

      Zornoza Indart, Ander; Pérez Herrera, Rosa Ana Upna Orcid; Elosúa Aguado, César Upna Orcid; Díaz Lucas, Silvia Upna Orcid; Bariáin Aisa, Cándido Upna Orcid; Loayssa Lara, Alayn Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (Optical Society of America, 2010)   Artículo / Artikulua  OpenAccess
      We propose a novel concept for hybrid networks that combine point and distributed Brillouin sensors in a cost-effective architecture that also deploys remote distributed Raman amplification to extend the sensing range. A ...

    • Optical fiber bus protection network to multiplex sensors: experimental validation of self-diagnosis 

      Pérez Herrera, Rosa Ana Upna Orcid; Urquhart, Paul; Schlüter, Marcel; Díaz Lucas, Silvia Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (IEEE, 2012)   Artículo / Artikulua  OpenAccess
      The experimental demonstration of a resilient wavelength division multiplexed (WDM) fiber bus network to interconnect sensors is reported. The network recovers operation after failures and it performs 'self-diagnosis', the ...

    • Resilient amplified double ring optical networks to multiplex optical fibre sensors 

      Fernández Vallejo, Montserrat Upna; Pérez Herrera, Rosa Ana Upna Orcid; Elosúa Aguado, César Upna Orcid; Díaz Lucas, Silvia Upna Orcid; Urquhart, Paul; Bariáin Aisa, Cándido Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (IEEE / OSA, 2009)   Artículo / Artikulua  OpenAccess
      We report the experimental demonstration of two configurations of an amplified optical fibre double ring network for the multiplexing of sensors. The networks are designed to be inherently resilient to fibre failures because ...

    • Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction 

      Del Villar, Ignacio Upna Orcid; Partridge, Matthew; Rodríguez Rodríguez, Wenceslao Eduardo; Fuentes Lorenzo, Omar Upna; Socorro Leránoz, Abián Bentor Upna Orcid; Díaz Lucas, Silvia Upna Orcid; Corres Sanz, Jesús María Upna Orcid; James, Stephen; Tatam, Ralph (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      The diameter of long-period fiber gratings (LPFGs) fabricated in optical fibers with a low cutoff wavelength was be reduced by hydrofluoric acid etching, enhancing the sensitivity to refractive index by more than a factor ...

    • Stable multi-wavelength erbium fiber ring laser with optical feedback for remote sensing 

      Díaz Lucas, Silvia Upna Orcid; Leandro González, Daniel Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (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 ...
