    • Generation of lossy mode resonances with different nanocoatings deposited on coverslips 

      Fuentes Lorenzo, Omar Upna; Goicoechea Fernández, Javier Upna; Corres Sanz, Jesús María Upna; Del Villar, Ignacio Upna; Ozcariz Celaya, Aritz Upna; Matías Maestro, Ignacio Upna (Optical Society of America, 2020)   Artículo / Artikulua  OpenAccess
      The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ...
    • Multimode – coreless – multimode fiber-based sensors: theoretical and experimental study 

      San Fabián García, Noé Upna; Socorro Leránoz, Abián Bentor Upna; Del Villar, Ignacio Upna; Díaz Lucas, Silvia Upna; Matías Maestro, Ignacio Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      This paper presents a complete study on the spectral behavior of a multimode-coreless-multimode fiber-optic structure, as well as its application as a refractometer and a liquid level sensor. The combination of two standard ...
    • Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array 

      Miguel Soto, Verónica de Upna; Jason, Johan; Kurtoglu, Deniz; López-Amo Sáinz, Manuel Upna; Wuilpart, Marc (Optical Society of America, 2019)   Artículo / Artikulua  OpenAccess
      A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...
