Schaltungsanordnung zur Dispersionskompensation in optischen Übertragungssystemen mit Hilfe von gechirpten Bragg-Gittern

摘要

In a dispersion compensating circuitry for optical transmission systems by means of chirped Bragg gratings, a plurality of Michelson interferometer stages each with an optical directional coupler and two chirped Bragg gratings form reflectors which completely reflect the light entering through the input optical waveguide to the output optical waveguide. The Michelson interferometer stages are interconnected in cascade so that the output optical waveguide of the interferometer of each stage passes into the input optical waveguide of the interferometer of the following stage.
