无偏压液晶盒中线虫分子的非相干相互作用
Incoherent interaction of nematicons in bias-free liquid-crystal cells
摘要：
实验研究了一对互不相干的向列型空间光孤子在双折射液晶中的传输动力学和相互作用。与以前的研究相比，我们考虑了无偏压的液晶盒，并比较了孤子相互作用在同向传播和反向传播的几何形状。我们分析了向列相互作用对输入功率的依赖性，并观察到一个直接的表现形式的远程非局域非线性。由于损耗引起的反向传播线虫孤子的功率不对称性，反向传播孤子的吸引比共传播线虫孤子需要更高的功率和更长的弛豫时间。
英文摘要：
We study experimentally the propagation dynamics and interaction of a pair of mutually incoherent nematicons: spatial optical solitons in nematic liquid crystals. In contrast to earlier studies, we consider a bias-free liquid-crystal cell and compare the soliton interaction in copropagating and counterpropagating geometries. We analyze the dependence of nematicon interaction on input power and observe a direct manifestation of a long-range nonlocal nonlinearity. Attraction of counterpropagating solitons requires higher powers and longer relaxation times than that of copropagating nematicons due to losses-induced power asymmetry of counterpropagating nematicons.
