Title: Method of manufacturing an optical fibre light waveguide

Abstract: A dielectric optical waveguide can be made by forming a bundle of rods in which a single rod made of glass suitable for forming the core of the dielectric optical waveguide is surrounded by three rods made of a glass suitable for forming the cladding of the dielectric optical waveguide. The bundle of rods is heated and drawn down to a suitable size. By increasing the number of rods in the bundle it is possible to make a dielectric optical waveguide with a plurality of cores.
