• BOTDA measurements tolerant to non-local effects by using a phase-modulated probe wave and RF demodulation 

      Urricelqui Polvorinos, Javier Upna Orcid; Sagüés García, Mikel Upna Orcid; Loayssa Lara, Alayn Upna Orcid (Optical Society of America, 2013)   Artículo / Artikulua  OpenAccess
      We demonstrate a Brillouin optical time domain analysis sensor based on a phase modulated probe wave and RF demodulation that provides measurements tolerant to frequency dependent variations of the pump pulse power induced ...
    • Dynamic BOTDA measurements based on Brillouin phase-shift and RF demodulation 

      Urricelqui Polvorinos, Javier Upna Orcid; Zornoza Indart, Ander; Sagüés García, Mikel Upna Orcid; Loayssa Lara, Alayn Upna Orcid (Optical Society of America, 2012)   Artículo / Artikulua  OpenAccess
      We demonstrate a novel dynamic BOTDA sensor based, for the first time to our knowledge, on the use of the Brillouin phase shift in addition to the conventional Brillouin gain. This provides the advantage of measurements ...
    • Phasorial differential pulse-width pair technique for long-range Brillouin optical time-domain analysis sensors 

      Urricelqui Polvorinos, Javier Upna Orcid; Sagüés García, Mikel Upna Orcid; Loayssa Lara, Alayn Upna Orcid (Optical Society of America, 2014)   Artículo / Artikulua  OpenAccess
      We introduce a novel phasorial differential pulse width pair (PDPP) method for Brillouin optical time domain analysis (BOTDA) sensors that combines spatial resolution enhancement with increased tolerance to non local ...
    • Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction 

      Urricelqui Polvorinos, Javier Upna Orcid; López Fernandino, Felipe; Sagüés García, Mikel Upna Orcid; Loayssa Lara, Alayn Upna Orcid (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...
    • Ultrafast electrooptic dual-comb interferometry 

      Durán, Vicente; Tainta Ausejo, Santiago Upna Orcid; Torres Company, Víctor (Optical Society of America, 2015)   Artículo / Artikulua  OpenAccess
      Dual-comb interferometry is a particularly compelling technique that relies on the phase coherence of two laser frequency combs for measuring broadband complex spectra. This method is rapidly advancing the field of optical ...
