Abstract
I report a lattice-form tunable optical dispersion compensator whose number of operable channels is doubled with the use of an interleave filter. In this scheme, interleaved signals are introduced into two different inputs of the lattice-form compensator and are provided with the same dispersion value based on unitary properties of the compensator transfer matrix. Thus this configuration can activate inoperable bands that account for nearly half of the total bandwidth in existing lattice-form compensators. The proposed compensator was realized by connecting the silica waveguide-based interleave filter and dispersion compensator with fibers. The dispersion of -283 to 252 ps/nm was obtained over 40 GHz bandwidth with a period of 50 GHz.
