Abstract
We report on the first experimental observation of photonic Bloch oscillations and Zener tunneling in
two-dimensional periodic systems. We study the propagation of an optical beam in a square lattice
superimposed on a refractive index ramp.We observe oscillations of the beam inside the first Brilloin zone
and tunneling of light from the first to the higher-order bands of the lattice band gap spectrum.
