Resonant Zener tunneling in two-dimensional periodic photonic lattices

Abstract

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 tunneling effect. Show more
