Photonic Crystal

Photonic Crystal
This is a scanning electron microscope image of a photonic crystal. The periodic arrangement of the holes in the material controls the movement of light within the crystal. A photonic crystal's highly ordered and repetitive structure affects the way light moves through it. Similar periodic arrangements are found in nature—for example, in precious opals and in the wings of the Blue Morpho butterfly—and scientists are studying these natural periodic structures to learn more about their properties and potential applications. These crystals have potential uses in computer engineering, lenses and optics, and variable-color paints and inks.
