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.
我们研究二维光子晶格中的齐纳隧穿,并针对六边形对称情况,推导了描述光子能带高对称点之间共振相互作用的广义朗道 - 齐纳 - 马约拉纳模型。我们证明了这种效应可用于产生弗洛凯 - 布洛赫模式,并通过对隧穿效应的直接数值模拟验证了该模型。
