Abstract

Photonic devices are provided comprising a photoactive layer and at least one additional layer, wherein a surface of the photoactive layer or a surface of the at least one additional layer has imprinted thereon a quasi-random pattern of nanostructures corresponding to a quasi-random pattern of nanostructures defined in a recording layer of a pre-written optical media disc. Methods of patterning a layer of a photonic device are also provided.
