Paper Abstract

Zero-average index metamaterials and photonic crystal superlattices are well known for presenting uncommon properties such as a new forbidden band for photons and self-collimation effect. In this work, we show how these two approaches can be combined to finely control beam propagation and we develop a theory that provides a comprehensive understanding of these phenomenon. We show that the curvature of the dispersion relation plays a crucial role to cancel light diffraction. This concept leads to the design of PhC superlattices with a very low filling factor in air and presenting a slow light regime. The frequency selectivity of the self-collimation effect is in addition shown to be increased by 10 or 50 compared to common 2D photonic crystal devices.
