Photonic Crystal Materials and Crystallography

Photonic crystals are periodic dielectric structures that are designed to form the energy band structure for photons, which either allows or forbids the propagation of electromagnetic waves of certain frequency ranges, making them ideal for light-harvesting applications (Maka et al., 2003). Applications:  Photonic crystals are attractive optical materials for controlling and manipulating light flow. One dimensional photonic crystal is already in widespread use, in the form of thin-film optics, with applications from low and high reflection coatings on lenses and mirrors to colour changing paints.
