Abstract: An anti-reflective article includes a substrate including a surface and a bulk, and an arrangement of anti-reflective nanostructures along the surface of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructures being supported by the bulk of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructure tapering from the bulk of the substrate to define a respective peak. At least some of the anti-reflective nanostructures of the arrangement of anti-reflective nanostructures are linked with an adjacent anti-reflective nanostructure of the arrangement of anti-reflective nanostructures via a respective interconnection. The respective interconnections are in addition to the bulk of the substrate supporting the anti-reflective nanostructures. The respective interconnections are disposed at or above a midpoint between the peaks of the anti-reflective nanostructures and the bulk of the substrate.
