Abstract
An optical component having a gradient refractive index produced by multiple windings of a glass fiber over a glass mandrel. The fiber is provided with a refractive index gradation which varies from an approximate match with the mandrel to selected lower values along its length thereby causing refractive index in the depth of windings to vary accordingly. Fusion and drawing of the mandrel and windings provide a rod (or fiber) of solid cross-section having a radial index gradient of predetermined profile.
