Abstract
A filtering device such as an optical interleaver/deinterleaver includes first and second optical couplers each having two inputs and two outputs. The inputs of the first coupler are adapted to receive input optical signals to be filtered and the outputs of the second coupler are adapted to provide filtered output optical signals. A first optical waveguide optically couples a first output of the first coupler to a first input of the second coupler. A second optical waveguide optically couples a second output of the first coupler to a second input of the second coupler. The filtering device also includes an optical resonator and a third optical coupler optically coupling the optical resonator to the second optical waveguide.
