Abstract:
1. An optical system, comprising: a polychromatic optical source for emitting an optical signal comprising a plurality of transverse modes of distinct transverse mode order, wherein each transverse mode has its own discrete wavelength; an optical link comprising at least one portion of multimode optical fiber having a graded-index core, wherein said multimode optical fiber has a nominal refractive index profile described by the relationship: where, an optical device positioned between said polychromatic optical source and an input of said multimode optical fiber; wherein, said optical device is suitable for spatially re-arranging the plurality of transverse modes dependent on the transverse mode order for coupling the energy of each of the transverse modes into a suitable propagation mode for at least partially compensating modal dispersion of said optical link with chromatic dispersion.
