Fundamental Comparative Study on Band-Gap Properties of 1-D Conventional Photonic Crystal and 1-D Function Photonic Crystal

Abstract

Photonic crystal is a kind of artificially material composed of two or more dielectrics arranged periodically, which can control the flow of photons due to the photonic band-gap. In this article, the band gap properties of the one-dimensional (1-D) conventional photonic crystal and the 1-D function photonic crystals are comparativly analyzed according to dispersion relation, periodicity and incident angle systematically. The results have some guiding significance for the 1-D photonic crystal and photonic crystal device fabrication.
