A broad-band and omnidirectional antireflection coating consisting of semiconductor nanowires is fabricated. The reflection is reduced due to a graded refractive index, which is achieved by a certain nanorod-length distribution of cylindrical and conically shaped rods. An increased transmission and, accordingly, a reduced reflection are demonstrated for the visible and near-infrared parts of the spectrum.
