Manufacturing of optical waveguides by embossing grooves by rolling

摘要

Optical waveguide and manufacturing of an optical waveguide comprising embossing at least two grooves into a first substrate by rolling, applying at least a second substrate into the grooves and covering at least the grooves with a third substrate such that the grooves constitute optical waveguides for optical signal transmission, and embossing a non guiding groove (600) between the at least two grooves (306).
