Abstract

We demonstrate the first fully controlled generation of immobile and slow spatial gap solitons in nonlinear periodic systems with band-gap spectra, and observe the key features of gap solitons that distinguish them from discrete solitons, including a dynamical transformation of gap solitons due to nonlinear interband coupling. We also describe theoretically and confirm experimentally the effect of the anomalous steering of gap solitons in optically induced photonic lattices.

摘要

我们展示了在具有带隙光谱的非线性周期系统中首次完全可控地产生静止和缓慢的空间隙孤子，并观察到隙孤子与离散孤子相区别的关键特征，包括由于非线性带间耦合导致的隙孤子的动力学转变。我们还从理论上进行了描述，并通过实验证实了光学诱导光子晶格中隙孤子的反常转向效应。
