25 September 2007 Self-collimation in photonic crystals with anisotropic constituents
Author Affiliations +
The equifrequency contours of a two-dimensional square lattice, Photonic Crystal(PhC) composed of an anisotropic cylinder in anisotropic medium are modeled and theoretically studied. The beam group velocity inside the PhC is determined as a function of input angle and from this data a quantitative measure of the self-collimation effect is deduced. The range of input angles for the self-collimation regime are significantly increased above those for a PhC composed of isotropic constituents.
