Novel tuneable filter based on MZ and an amplified ring resonator for OFDM networks
MetadataShow full item record
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 achieved.

Vargas, Salvador; Vázquez, Carmen; Pena, José Manuel; Corredera, Pedro (2003-07-28)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 ...
