Chromatic dispersion is efficiently compensated in a compact device by combining a spatial mode converter with a dispersive waveguide having a dispersion characteristic of substantially equivalent magnitude, and opposite sign, to the desired amount of dispersion to be compensated. The spatial mode converter...http://www.google.fr/patents/US5185827?utm_source=gb-gplus-shareBrevet US5185827 - Apparatus for compensating chromatic dispersion in optical fibers
