我们报道了在强耦合状态下工作的相干泵浦平面半导体微腔中激子极化子的二维局域化。二维极化孤子存在，尽管在平面正交方向上色散符号相反。补偿相反色散的非线性有不同的物理根源，是由于一边的极化子排斥和另一边的参数四波混频。这两种非线性都可以支持它们各自的一维孤子族，它们彼此共存，并与二维孤子共存。
We report two-dimensional localization of exciton polaritons in a coherently pumped planar semiconductor microcavity operating in the strong-coupling regime. Two-dimensional polariton solitons exist despite the opposite dispersion signs along the orthogonal in plane directions. Nonlinearities compensating the opposing dispersions have different physical origins and are due to the repulsion of polaritons on one side and due to parametric four-wave mixing on the other. Both of these nonlinearities can support their respective families of one-dimensional solitons, which coexist with each other and with the two-dimensional solitons.
