Abstract
A method for creating an optical structure includes forming a layer of chalcogenide material upon a substrate, and applying a patterned stamper to the layer of chalcogenide material, in the presence of heat, the patterned stamper causing the layer of chalcogenide material to reflow such that stamped features of the patterned stamper are transferred onto the layer of chalcogenide material. The stamped features onto the layer of chalcogenide material are used to form one of an optical waveguide, an optical mirror, digital video disk data, compact disk data and combinations comprising at least one of the foregoing.
