Photonic crystals are the periodical dielectric structured electromagnetic media with multi-functions for light wave propagating and processing, including optical forbidden band gap, localized permitted propagating state, super-large refractive index, super-strong dispersion, nonlinear optical effect, and negative refractive index effect which can be constructed with refractive index engineering artificially. Different kinds of devices and functional chips can be fabricated with photonic crystal materials and will have wide applications in the field of information high technology as presented in this paper.
