چکیده
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.

Zener tunneling in two-dimensional photonic lattices.
We discuss the interband light tunneling in a two-dimensional periodic photonic structure, as studied recently in experiments for optically induced photonic lattices [Trompeter, Phys. Rev. Lett. 96, 053903 (2006)]. We identify the Zener tunneling regime at the crossing of two Bloch bands, which occurs in the generic case of a Bragg reflection when the Bloch index crosses the edge of the irreduc...
متن کاملResonant Zener tunneling in two-dimensional periodic photonic lattices.
We study Zener tunneling in two-dimensional photonic lattices and derive, for the case of hexagonal symmetry, the generalized Landau-Zener-Majorana model describing resonant interaction between high-symmetry points of the photonic spectral bands. We demonstrate that this effect can be employed for the generation of Floquet-Bloch modes and verify the model by direct numerical simulations of the ...
متن کاملInterband resonant transitions in two-dimensional hexagonal lattices: Rabi oscillations, Zener tunnelling, and tunnelling of phase dislocations.
We study, analytically and numerically, the dynamics of interband transitions in two-dimensional hexagonal periodic photonic lattices. We develop an analytical approach employing the Bragg resonances of different types and derive the effective multi-level models of the Landau-Zener-Majorana type. For two-dimensional periodic potentials without a tilt, we demonstrate the possibility of the Rabi ...
متن کاملBloch Waves and Bloch Bands of Bose-Einstein Condensates in Optical Lattices
Bose-Einstein condensates (BECs) in optical lattices have been attracting increasing attention from both theorists [1, 2, 3, 4, 5, 6, 7] and experimentalists [8, 9]. People are interested in how the interaction and coherence of this system affect the interesting phenomena observed with dilute cold atoms in optical lattices [10], such as LandauZener tunneling and Bloch oscillations. Recent studi...
متن کاملBloch–Zener Oscillations in Graphene and Topological Insulators
We show that superlattices based on zero-gap semiconductors such as graphene and mercury telluride exhibit characteristic Bloch–Zener oscillations that emerge from the coherent superposition of Bloch oscillations and multiple Zener tunneling between the electron and hole branch. We demonstrate this mechanism by means of wave packet dynamics in various spatially periodically modulated nanoribbon...
