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 exchange the optical energy from one propagating spatial mode to another spatial mode whose propagation is supported by the multimode or dual-mode fiber. This apparatus is applicable to lightwave repeaters, regenerators, transmitters, and receivers.
