    • Fiber cavity ring down and gain amplification effect 

      Silva, Susana; Magalhães, Regina; Pérez Herrera, Rosa Ana Upna; López-Amo Sáinz, Manuel Upna; Marques, M. B.; Frazão, Orlando (Springer Nature, 2016)   Artículo / Artikulua  OpenAccess
      The effect of an erbium-doped fiber amplifier (EDFA) placed inside the fiber ring of a cavity ring down (CRD) configuration is studied. The limitations and advantages of this configuration are discussed, and the study of ...
    • 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 ...
