Abstract

We report a computational study of how light propagates within a self-collimating, hexagonal photonic crystal. The photonic crystal can be described as a two-dimensional hexagonal lattice of air holes extruded into the third dimension. While traveling inside the device, light is forced by self-collimation to propagate along the extrusion direction. Finite-difference time-domain calculations show that the lattice must have at least four rings of unit cells surrounding the innermost unit cells where light is centered for it to propagate under strong self-collimation, with low scattering loss.
