Coupled waveguide modes in hexagonal photonic crystals

Brownless, J Scott; Mahmoodian, Sahand; Dossou, Kokou B; Lawrence, Felix J; Botten, Lindsay; de Sterke, C Martijn


We investigate the modes of coupled waveguides in a hexagonal photonic crystal. We find that for a substantial parameter range the coupled waveguide modes have dispersion relations exhibiting multiple intersections, which we explain both intuitively and using a rigorous tight-binding argument.
