Paper Abstract

A model is proposed to realize light collimation by surface modes that propagate on a corrugated surface around the output of a photonic crystal (PhC). The dispersion relation of the surface corrugation is given for a number of surface terminations. Self-collimation effect simulation can be obtained compared to the structure without surface corrugation. Precision collimation is shown at the chosen frequency, which matches with the self-collimation frequency in the PhCs.
