ABSTRACT:
An antireflection surface formed using a plurality of nanostructures of a first material on a surface of a second material. The first material is different from the second material. The distribution of spatial periods of the nanostructures is set by a self-assembly operation. The surface of the second material is converted to operate as a graded index surface that is substantially antireflective for the wavelength of interest.
