Paper Abstract

Results that characterize a fast-diffusing titania silicate gradient-index (GRIN) glass in a sodium (Na + ) for lithium (Li + ) ion exchange are presented. Manufacturing challenges associated with diffusion in titania silicate glass are addressed in order to extend its manufacturability to large-diameter radial diffusions. Two 20-mm diameter radial GRIN lenses have been fabricated in less than 4-weeks diffusion time, demonstrating the potential for fabricating large-diameter radial GRIN glass elements.
