A planar plasmonic device includes a first material layer having a surface configured to receive at least one photon of incident light. A patterned plasmonic nanostructured layer is disposed adjacent and optically coupled to the first material layer. The patterned plasmonic nanostructured layer includes a selected one of: a) at least a portion of a surface of the patterned plasmonic nanostructured layer includes a textured surface, and b) at least one compound nanofeature including a first material disposed adjacent to a second material within the compound nanofeature.
