Abstract
Dispersion is reduced in a graded index optical fiber having a finite number of core layers by introducing slow longitudinal variations into the index of refraction of each layer. The index of refraction of each layer varies between a maximum which is proximate in value to the minimum index of refraction of the more central radially adjacent layer and a minimum which is proximate in value to the maximum index of refraction of the next furthermost radially adjacent layer.
