Abstract
In a method for directly drawing a glass optical waveguide or waveguide blank from two or more reservoirs of molten glass wherein a relatively high refractive index glass core member is clad with a relatively low refractive index glass cladding, control over the refractive index variations occurring due to the migration of dopants between the core and cladding is obtained by providing one or more glass diffusion layers between the core and cladding.
