Abstract:
A method for compensating for the dispersion of co-transmitted optical signals having different wavelengths,wherein the transmitted optical signals are mutually coupled into an arrangement composed of optically interconnected photonic crystals, which are positioned one after another on at least one waveguide; in each photonic crystal, only those signals of one wavelength are reflected or diverted, and the signals of the other wavelengths are transmitted, unattenuated, to be downstream photonic crystal; wherein for the signals of each wavelength, the path length from the point of in-coupling to the point in the respective photonic crystal where they are reflected or defected, is acted upon by a negative dispersion, which alter or completely cancels the positive dispersion of the coupled-in signals, and the resulting signals of all wavelengths are subsequently further co-transmitted.
