Abstract
| - With planar photolithography and self-assembly techniques, multilayer colloidal crystals with a woodpile structurewere fabricated. They represent a new kind of photonic crystals, that is, three-dimensional (3D) photonic crystals witha dual periodicity; one comes from the face-centered cubic (fcc) structure within the colloidal crystal strips and theother one results from the periodic arrangement of the colloidal crystal strips.
