摘要：
An optical device includes a substantially planar substrate and a lens array disposed on the substantially planar substrate. The lens array is formed of a plurality of distinct sub-wavelength gratings, in which the sub-wavelength gratings are selected to produce a desired phase change in beams of light that are at least one of reflected and refracted by the sub-wavelength gratings of the lens array.
