Abstract :
For multi-channel compensation of residual chromatic dispersion we present a compact equalizer which can easily be realized in planar waveguide technology such as silicon-on-insulator (SOI). We show the design of this two-stage architecture and analyze the improvement in controllability by adding only one tunable coupler.
