Abstract

In recent years, a growing interest appeared in the systems that can provide a either a reduction of the speed of light, slow-light, or a superluminal light propagation. Experiments have confirmed the existence of both behaviors in three-dimensional ordered nanostructures, in the spectral range where the wavelength of light is on the order, or smaller, than the lattice constant [1]. Using periodic boundary conditions in a band structure calculation of a perfect 3D photonic crystal one finds that, in such frequency range, only propagating modes with a vanishing slope dispersion relation exist and, hence, a reduced group velocity is predicted [2].
