Method for drawing high-bandwidth optical waveguides |
| abstract |
Abstract of the Disclosure 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 refrac-tive index variations occurring due to the migration of dopants between the core and cladding is obtained by pro-viding one or more glass diffusion layers between the core and cladding. |
