Abstract
A method for making an optical fiber solid rod preform wherein a vapor reaction deposit process is used to form a localized deposit on an end face of a rod or disc by relative movement in which the position of the localized deposit is scanned over the end face of the solid rod or disc and at the same time the reaction is progressively changed to cause the deposit building up on the end face to have a radially graded refractive index profile.
