Abstract
Structures for scattering light at multiple wavelengths are disclosed. Scattering elements are fabricated with different geometric dimensions and arrangements, to scatter or focus light at the same focal distance for each wavelength, or at different focal distances according to the desired application. Scattering elements can be circular or elliptical posts, allowing polarization dependent scattering. The elements can have different orientations to scatter light from multiple wavelengths at the desired focal length.
