LOW LOSS OPTICAL WAVEGUIDES INSCRIBED IN MEDIA GLASS SUBSTRATES, ASSOCIATED OPTICAL DEVICES AND FEMTOSECOND LASER-BASED SYSTEMS AND METHODS FOR INSCRIBING THE WAVEGUIDES

摘要

The method for inscribing a waveguide into a glass substrate generally has the steps of: relatively moving a femtosecond laser beam along a surface of the glass substrate while maintaining the focus of the laser beam at a given depth from the surface, wherein the glass substrate is a toughened glass. The optical device generally has: a glass substrate of toughened glass having a waveguide inscribed therein at a given depth from a surface of the glass.
