ABSTRACT:
The invention relates to an interleaver circuit (10, 10′) for interleaving optical signals, comprising a first and a second input port (12, 14), an output port (16), a first optical filter (18; 18′) that has a first filter function with periodic passbands (32, 34, 36) and is connected to the first input port (12), a second optical filter (20; 20′) that has a second filter function with periodic passbands (38, 40) and is connected to the second input port (14), and an optical interleaver (22). The latter comprises a multiplexing port (23) connected to the output port (16) and two de-multiplexing ports (24, 26) connected to the first input port (12) via the first optical filter (18; 18′) and the second optical filter (20; 20′), respectively. At least one optical filter (18, 20; 18′, 20′) is tunable such that the passband frequencies are collectively shiftable without altering the periodicity of the filter function.
