Photonic crystals were dielectric structures modulated periodically on the scale of optical wavelength. Under specific conditions, they can exhibit a forbidden band of frequencies, a photonic band gap (PBG). The existence of a PBG gives rise to a number of interesting and useful properties. So photonic crystals were the focus of global research and development efforts. This paper presented some characteristics of photonic crystals, the ways for tuning PBG and the methods for preparation of threedimensional photonic crystals.
