Two fundamental laser physics phenomena--dissipative soliton and polarisation of light are recently merged to the concept of vector dissipative soliton (VDS), viz. train of short pulses with specific state of polarisation (SOP) and shape defined by an interplay between anisotropy, gain/loss, dispersion, and nonlinearity. Emergence of VDSs is both of the fundamental scientific interest and is also a promising technique for control of dynamic SOPs important for numerous applications from nano-optics to high capacity fibre optic communications. Using specially designed and developed fast polarimeter, we present here the first experimental results on SOP evolution of vector soliton molecules with periodic polarisation switching between two and three SOPs and superposition of polarisation switching with SOP precessing. The underlying physics presents an interplay between linear and circular birefringence of a laser cavity along with light induced anisotropy caused by polarisation hole burning.
两种基本的激光物理现象——耗散孤子和光的偏振，最近融合到了矢量耗散孤子（VDS）的概念中，即具有特定偏振态（SOP）和形状的短脉冲序列，其由各向异性、增益/损耗、色散和非线性之间的相互作用所定义。矢量耗散孤子的出现既具有重要的基础科学意义，也是一种很有前景的技术，可用于控制动态偏振态，这对于从纳米光学到高容量光纤通信等众多应用都非常重要。通过使用专门设计和开发的快速偏振计，我们在此展示了关于矢量孤子分子偏振态演化的首批实验结果，该演化涉及在两种和三种偏振态之间的周期性偏振切换以及偏振切换与偏振态进动的叠加。其 underlying physics 呈现出激光腔的线性和圆双折射与由偏振烧孔引起的光致各向异性之间的相互作用。 （注：原文中“underlying physics”直接保留英文未翻译，可能是特定术语或有错误，这里按原文呈现）
