Abstract
Methods of patterning a layer of a photonic device are provided using stamps or masks derived from pre-written optical media discs. One method comprises pressing a stamp on a surface of a layer of a photonic device, the stamp comprising a stamping surface which defines a negative replica of a quasi-random pattern of nanostructures defined in a recording layer of a pre-written optical media disc, for a period of time sufficient to imprint the quasi-random pattern of nanostructures defined in the recording layer of the pre-written optical media disc onto the surface of the layer of the photonic device; and removing the stamp. The stamps, the masks, and the photonic devices comprising the patterned layers are also provided.
