Photonic crystals are, in essence, an exploded view into the world of atomic-scale crystals. Instead of atoms, nanospheres of any number of materials can be arranged into a crystal with patterns on the order of the wavelength of light—about 400nm to 700nm for visible light, although photonic crystals are not limited to these wavelengths. Researchers have created precisely positioned arrays of self-assembling photonic crystals with a little help from semiconductor fabrication technology or capillary action, moving us another step closer to highly integrated devices that use photonic crystals.
