• An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber 

      Rota Rodrigo, Sergio Upna; Rodrigues Pinto, Ana Margarida Upna; Bravo Acha, Mikel Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (MDPI, 2013)   Artículo / Artikulua  OpenAccess
      A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of the sensing ...
    • Mode transition in complex refractive index coated single-mode–multimode–single-mode structure 

      Socorro Leránoz, Abián Bentor Upna Orcid; Del Villar, Ignacio Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Optical Society of America, 2013)   Artículo / Artikulua  OpenAccess
      By coating a single-mode–multimode–single-mode (SMS) structure with a high refractive index thin-film it is possible to obtain a transition of modes for specific combinations of thin-film thickness, thinfilm refractive ...
    • Refractometric sensors based on multimode interference in a thin-film coated singlemode– multimode–single-mode structure with reflection configuration 

      Del Villar, Ignacio Upna Orcid; Socorro Leránoz, Abián Bentor Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Optical Society of America, 2014)   Artículo / Artikulua  OpenAccess
      Thin-film coated single-mode–multimode–single-mode (SMS) structures have been analyzed both theoretically and experimentally with the aim of detecting different refractive indices. By adequate selection of the thickness ...
    • Sensors based on thin-film coated cladding removed multimode optical fiber and single-mode multimode single-mode fiber: a comparative study 

      Del Villar, Ignacio Upna Orcid; Socorro Leránoz, Abián Bentor Upna Orcid; Hernáez Sáenz de Zaitigui, Miguel Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Ruiz Zamarreño, Carlos Upna Orcid; Sánchez Zábal, Pedro Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Hindawi Publishing Corporation, 2015)   Artículo / Artikulua  OpenAccess
      Two simple optical fibre structures that do not require the inscription of a grating, a cladding removed multimode optical fibre (CRMOF) and a single-mode multimode single-mode structure (SMS), are compared in terms of ...
