    "abstract": "We generate experimentally different types of two-dimensional Bloch waves of\na square photonic lattice by employing the phase imprinting technique. We probe\nthe local dispersion of the Bloch modes in the photonic lattice by analyzing\nthe linear diffraction of beams associated with the high-symmetry points of the\nBrillouin zone, and also distinguish the regimes of normal, anomalous, and\nanisotropic diffraction through observations of nonlinear self-action effects.",
