Abstract
The invention is a method of making an optical fiber or cane (,) that has optical properties that vary axially. Core glass (,) and clad glass (,) are fed into a furnace to form the cane or fiber. The velocities of the feeding of the clad and core are controlled so that the total combined mass per unit time is constant. The diameter of the core (,) varies along the length of the fiber or cane in accordance with the control of the velocities. The variance in the core diameter results in the variance of the axial optical properties of the fiber or cane.
