N2 - A procedure for obtaining coupled-mode equations in low-contrast nonlinear photonic crystals periodic in one, two or three dimensions (3D) by using the method of multiple scales is developed. It is found that for three coupled modes in a two-dimensional (2D) hexagonal lattice, coupled-mode equations (CME) are obtained. By solving the CME numerically, the limiting behavior of a hexagonal lattice was found. The results show that two dimensional (2D) low-contrast nonlinear photonic crystals support intensity-dependent diffraction and optical limiting.
