Abstract:
1. An apparatus, comprising: an input variable optical coupler including output ports, the input variable optical coupler coupled to selectively split portions of an optical signal received from an optical input port into each of the output ports; optical dispersion paths each coupled to one of the output ports of the input variable optical coupler to impart dispersion compensation to each of the split portions of the optical signal, wherein each of the optical dispersion paths includes a bus waveguide and a plurality of cascaded racetrack resonators optically coupled along the bus waveguide; an output variable optical coupler including input ports each coupled to one of the optical dispersion paths to selectively combine the split portions of the optical signal; and an optical output port coupled to the output variable optical coupler to output a dispersion compensated optical signal.
