Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
(2007-11-12)
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
(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 ...
Measurements on passive tunable optical filters for DWDM
(2002-06-06)
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 ...
