• Measurements on passive tunable optical filters for DWDM 

      Vázquez, Carmen; Vargas, Salvador; Sánchez Pena, José Manuel; Corredera, Pedro (06/06/2002)
      Measurements on a passive optical fibre tunable filter are presented. The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a coupler. The novel ...
    • Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM 

      Vargas, Salvador; Vázquez, Carmen; Sánchez Pena, José Manuel (11/12/2001)
      A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...
    • Tunable optical filters using compound ring resonators for DWDM 

      Vargas, Salvador; Vázquez, Carmen; Pena, José Manuel; Corredera, Pedro (07/28/2003)
      The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the ...
