Coupled waveguide modes in hexagonal photonic crystals

Opt Express. 2010 Nov 22;18(24):25346-60. doi: 10.1364/OE.18.025346.

Abstract

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.
