Abstract
It has been found that in a profiled optical waveguide for guiding a finite spectrum of light, reduction of total dispersion is possible by forming the overall profile in the waveguide as a composite of at least two profiles of different contour. The profiles contributing to the composite are formed for example through polarizability or density gradations in the waveguide.
