This2 2dispersion compensator should compensate for the dispersion of a single wavelength channelwith a bandwidth of 0.4 nm, corresponding to 40 GHz at 1.55μm wavelength, and be integratedinto a silicon chip, in order to be compatible with other electrical and optical integrated devices.Due to the small thickness of the silicon core and the high index contrast between the core andthe oxide claddings, the behavior of the IOSOI system is fully three dimensional and combinesthe properties of a two dimensional photonic crystal with those of a planar waveguide.
