摘要：Photonic crystal (PhC) is a new class of material which has a periodic modulation of dielectric constant. PhC will exhibit superprism effect, negative refraction and self-collimating ultra-low group velocity due to the anomalous dispersion of PhC. We can utilize the characters of photonic bandgap(PBG), defect band, pass band and band edge to control the propagation of the light. This research was to investigate the refraction and superprism effect of photonic crystals. The study background and the basic theories of photonic crystals were introduced. The refraction of photonic crystals and superprism effect were discussed with the correlating knowledge and the computing methods. A new theory of light refraction at the surface of a photonic crystal was put forward and simulated. The simulating results of this application for negative refraction and superprism effect were demonstrated by some simulating figures. These may bring about important potential applications in some areas.
