Properties of photonic bandgap in one-dimensional mutlicomponent photonic crystal

Properties of photonic band gap and light propagation in one-dimensional multicomponent photonic crystal have been studied with the optical transfer matrix method. We mainly analyze the relation of photonic band-gap property with the arrangement of components, the refractive index and the geometrical thickness. In this study,the methods to change the width and the location of the existing photonic band-gaps in multicomponent photonic crystal are proposed.
