Circuit structure for dispersion compensation in optical communication systems by means of an optical filter

摘要

In a circuit arrangement for dispersion compensation in optical transmission systems by means of an optical filter, an optical transverse filter is provided as a negative dispersion filter, and which has a series of directional couplers which respectively follow one another at a spacing of tau /2 and are operated as splitters. A series of directional couplers are provided which likewise follow one another at a spacing of tau /2 and are operated as combiners, the second output of each directional coupler of the directional couplers operated as splitters leading in each case to the second input of the respectively corresponding directional coupler operated as a combiner.
