Dynamic diffraction and interband transitions in two-dimensional photonic lattices. Academic Article uri icon


  • We reveal a direct link between two fundamental wave phenomena in periodic media, Pendellsung oscillations and resonant coupling between spectral bands. We experimentally measure the power transfer between laser beams associated with the high-symmetry points in periodic and biased hexagonal photonic lattices. As a result, we demonstrate that Pendellsung oscillations dominate the dynamics of resonant interband transitions on a short propagation scale.
