Photonic Band Gap
A Photonic Band Gap material is also known as photonic crystals. It is a structure that could manipulate beams of light in the same way semiconductors control electric currents. Photonic Band Gap materials have a band gap due to a periodicity in the materials dielectric properties. Photonic crystals usually consist of di electric materials, that is, materials that serve as electrical insulators or in which an electromagnetic field can be propagated with low loss. Photonic Band Gap materials can prevent light of certain frequencies or wavelengths from propagating in one, two or any number of polarization directions within the materials.
