    • Arc-induced long period fiber gratings in the dispersion turning points 

      Colaço, Celso; Caldas, Paulo; Del Villar, Ignacio Upna; Chibante, Rui; Rego, Gaspar (IEEEOptical Society of America, 2016)   Artículo / Artikulua  OpenAccess
      We demonstrated the possibility to inscribe longperiod fiber gratings (LPFGs) in a B/Ge codoped fiber by using grating periods shorter than 150 μm. We also have arc-induced in the SMF 28 fiber an LPFG in the dispersion ...
    • Etched LPFGs in reflective configuration for sensitivity and attenuation band depth increase 

      Del Villar, Ignacio Upna; Socorro Leránoz, Abián Bentor Upna; Corres Sanz, Jesús María Upna; Matías Maestro, Ignacio Upna; Cruz, José Luis; Rego, Gaspar (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      A reflection configuration setup for long-period fiber gratings is presented. It permits to obtain a unique band with attenuation double than that obtained in transmission configuration, which is interesting for ...
