Abstract

We experimentally demonstrate and model dark spatial solitons in azo-doped liquid crystals, in the presence of saturation and nonlocality of the effective nonlinearity due to changes in molecular order. The guiding properties of dark solitons are probed with a weak input of different wavelength.

摘要

我们通过实验演示和建模，研究了由于分子排列变化导致有效非线性的饱和和非局域性，在偶氮掺杂液晶中产生的暗空间孤子。通过不同波长的弱输入探测暗孤子的引导特性。
