    • Etched and nanocoated single-mode multimode single-mode (SMS) fibers for detection of wind turbine gearbox oil degradation 

      Del Villar, Ignacio Upna; Goñi Carnicero, Jaime; Vicente Gómara, Adrián; Arregui San Martín, Francisco Javier Upna; Matías Maestro, Ignacio Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      The application of an etching process in a single-mode multimode single-mode (SMS) fiber allows monitoring the change of refractive index of wind turbine gearbox oil due to temperature and degradation with a limitation at ...
    • Fiber-based early diagnosis of venous thromboembolic disease by label-free D-dimer detection 

      Zubiate Orzanco, Pablo Upna; Urrutia Azcona, Aitor Upna; Ruiz Zamarreño, Carlos Upna; Egea Urra, Josune; Fernández Irigoyen, Joaquín; Giannetti, Ambra; Baldini, Francesco; Díaz Lucas, Silvia Upna; Matías Maestro, Ignacio Upna; Arregui San Martín, Francisco Javier Upna; Santamaría, Enrique; Chiavaioli, Francesco; Del Villar, Ignacio Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
    • Generation of lossy mode resonances in planar waveguides toward development of humidity sensors 

      Fuentes Lorenzo, Omar; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna; Del Villar, Ignacio Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      Lossy mode resonances (LMRs) are typically obtained with optical fibre. The Kretschmann configuration is an alternative but LMRs are generated with angles approaching grazing incidence. In this work, a new setup is explored, ...
    • Generation of lossy mode resonances with different nanocoatings deposited on coverslips 

      Fuentes Lorenzo, Omar; 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 ...
    • Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides 

      Fuentes Lorenzo, Omar; Del Villar, Ignacio Upna; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna (Nature Research, 2019)   Artículo / Artikulua  OpenAccess
      The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ...
    • Trends in the design of wavelength-based optical fibre biosensors (2008–2018) 

      Socorro Leránoz, Abián Bentor Upna; Santano, Desiree; Del Villar, Ignacio Upna; Matías Maestro, Ignacio Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      During the last decades, both governments and companies have been committed to the continuous checking of biological parameters, which can prevent extra costs to administrations. A very efficient way to address this issue ...
