Abstract
An optical waveguide article includes a base layer formed from a first glass composition with a refractive index nand a surface layer fused to the base layer and formed from a second glass composition with a refractive index n. A waveguide is disposed within the surface layer. nand nsatisfy the equation |n−n|≥0.001. A method for forming an optical waveguide article includes forming a waveguide in a surface layer of a glass laminate structure including a base layer fused to the surface layer. The base layer is formed from a first glass composition with a refractive index n. The surface layer is formed from a second glass composition with a refractive index n. nand nsatisfy the equation |n−n|≥0.0001.
