Using a passive, coherently driven nonlinear optical fiber ring resonator, we report the experimental realization of dissipative polarization domain walls. The domain walls arise through a symmetry breaking bifurcation and consist of temporally localized structures where the amplitudes of the two polarization modes of the resonator interchange, segregating domains of orthogonal polarization states. We show that dissipative polarization domain walls can persist in the resonator without changing shape. We also demonstrate on-demand excitation, as well as pinning of domain walls at specific positions for arbitrary long times. Our results could prove useful for the analog simulation of ubiquitous domain-wall related phenomena, and pave the way to an all-optical buffer adapted to the transmission of topological bits.

无源相干驱动的Kerr谐振器中的耗散极化畴壁

使用无源，相干驱动的非线性光纤环形谐振器，我们报告了耗散极化畴壁的实验实现。畴壁通过对称破坏分叉而出现，并且由时间局部结构组成，在该结构中，谐振器的两个极化模式的振幅互换，从而隔离了正交极化状态的畴。我们表明，耗散极化畴壁可以在谐振器中持续存在而不会改变形状。我们还演示了按需激励，以及任意长时间长时间将磁畴壁固定在特定位置上的情况。我们的结果可能被证明对普遍存在的域壁相关现象的模拟非常有用，并为适应拓扑位传输的全光缓冲器铺平了道路。
