Abstract: We study theoretically the dispersion properties of Bloch modes and nonlinearly-induced defect states in two-dimensional waveguide arrays. We define the conditions for achieving anomalous group-velocity dispersion and discuss possibilities for generation of spatiotemporal solitons.
Keywords: wave-guide arrays; photonic bandgap fiber; spatial solitons; discrete solitons; optical solitons; lattices; bullets; localization; propagation; diffraction
