    • 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 ...

    • Novel tuneable filter based on MZ and an amplified ring resonator for OFDM networks 

      Vargas, Salvador; Vázquez, Carmen (1999-11-08)
      A novel reconfigurable fibre based tuneable filter is proposed. The module relies on a cascaded connection of Mach-Zehnders and an amplified fibre ring resonator. MHz range adjustable FHWM bandwidths and high crosstalk are ...

    • Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator 

      Vargas, Salvador; Vázquez, Carmen (11/12/2007)
      We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions ...

    • 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 ...
