Effect of nonlinearity on dynamic diffraction and interband coupling in two-dimensional hexagonal photonic lattices

Terhalle, Bernd; Desyatnikov, Anton S; Neshev, Dragomir; Denz, Cornelia; Kivshar, Yuri; Krolikowski, Wieslaw


We explore experimentally the effect of nonlinearity on resonant coupling between high-symmetry momentum states in hexagonal photonic lattices. We observe nonlinear Pendellösung oscillations with the power-dependent excitation of additional critical poin
