Abstract

Band-gap structure of periodic waveguide arrays is investigated in the linear and the nonlinear regimes. Excitation of array modes belonging to high bands is demonstrated. Floquet-Bloch solitons are demonstrated experimentally and shown to be a generalization of discrete solitons.

摘要

研究了周期波导阵列在线性和非线性区域的带隙结构。展示了属于高频带的阵列模式的激发。通过实验证明了弗洛凯 - 布洛赫孤子，并表明它们是离散孤子的推广。
