Abstract

We demonstrate, experimentally and theoretically, surface-wave solitons occurring at the interface between a dielectric medium (air) and a nonlinear material with a very long-range nonlocal response. These surface solitons are always attracted toward the surface, and unlike their Kerr-like counterparts, they do not exhibit a power threshold.

摘要

我们通过实验和理论证明，在电介质介质（空气）与具有极长程非局域响应的非线性材料之间的界面处会出现表面波孤子。这些表面孤子总是被吸引向表面，并且与类似克尔效应的孤子不同，它们没有功率阈值。
