    • Development of new punctual optical fiber transducer for sensing 

      López Aldaba, Aitor Upna (2018)   Tesis doctoral / Doktoretza tesia  OpenAccess
      The international research community has been nurturing photonic technologies over the years, aiming to develop cost effective solutions for a number of applications. Optical fibers offer an efficient solution for sensing ...
    • Micro-displacement sensor based on a hollow-core photonic crystal fiber 

      Rodrigues Pinto, Ana Margarida Upna; López-Amo Sáinz, Manuel Upna; Baptista, José Manuel; Santos, José Luís; Frazão, Orlando (MDPI, 2012)   Artículo / Artikulua  OpenAccess
      A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment ...
    • Multiwavelength Raman fiber lasers using Hi-Bi photonic crystal fiber loop mirrors combined with random cavities 

      Rodrigues Pinto, Ana Margarida Upna; Frazão, Orlando; Santos, José Luís; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2011)   Artículo / Artikulua  OpenAccess
      Different multiwavelength Raman fiber lasers based on a hybrid cavity set-up are proposed. The lasing schemes are based in highly birefringent photonic crystal fiber loop mirrors combined with random cavities. The Hi-Bi ...
    • Photonic crystal fiber temperature sensor based on quantum dot nanocoatings 

      Larrión Zabaleta, Beatriz Upna; Hernáez Sáenz de Zaitigui, Miguel Upna; Arregui San Martín, Francisco Javier Upna; Goicoechea Fernández, Javier Upna; Bravo Larrea, Javier Upna; Matías Maestro, Ignacio Upna (Hindawi / Wiley, 2009)   Artículo / Artikulua  OpenAccess
      Quantum dot nanocoatings have been deposited by means of the Layer-by-Layer technique on the inner holes of Photonic Crystal Fibers (PCFs) for the fabrication of temperature sensors. The optical properties of these sensors ...
    • Photonic crystal fibers for sensing applications 

      Rodrigues Pinto, Ana Margarida Upna; López-Amo Sáinz, Manuel Upna (Hindawi Publishing Corporation, 2012)   Artículo / Artikulua  OpenAccess
      Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers present ...
    • Simultaneous measurement of strain and temperature based on clover microstructured fiber loop mirror 

      Pérez Herrera, Rosa Ana Upna; André, R. M.; Silva, S. F.; Becker, M.; Schuster, K.; Kobelke, J.; López-Amo Sáinz, Manuel Upna; Santos, José Luís; Frazão, Orlando (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      In this work, two all-fiber loop mirrors using a clover microstructured fiber for the simultaneous measurement of temperature and strain are presented. The sensing heads are formed by a short piece of clover microstructured ...
