Research article (journal)Abstract
We reveal a direct link between two fundamental wave phenomena in periodic media, Pendellosung 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 Pendellosung oscillations dominate the dynamics of resonant interband transitions on a short propagation scale.
