Abstract: Photonic crystals are a new type of artificial materials with multi-dimensionally periodic dielectric
structures. They can create a range of forbidden frequencies called photonic bandgap. Photons with energy lying in the gap cannot propagate through the
medium. This has the fascinating prospect to shape and mould the flow of light for photonic information technology, and thus makes photonic crystals
one of the hottest research fields nowadays. In this article the author will review the band structures, anticipated applications and preparation
methods of photonic crystals.

Key words: photonic crystals, photonic band gap, periodicity in dielectric constant
