Abstract
A process is described for forming glass optical fibers by heating a glass composition to vaporize a component of the composition at the surface to reduce the refractive index of the glass surface. Four alternative processes can be used: heat treating a fiber preform followed by drawing the fiber, simultaneous heat treating and fiber pulling from a glass melt, fiber pulling followed by heat treating or heat treating the surface of a melt followed by drawing a fiber or preform so that the surface of the melt comprises the cladding.
