论文摘要
我们模拟了在TE-TM分裂的情况下，在排列在六边形环分子中的半导体微柱中的激子 - 孔子冷凝物中的涡流模式的生成。这种分裂提高了方位角调制的涡流模式的退化，并具有相反的拓扑费，并由该结构支撑，因此出现了两个偏振分量中拓扑电荷不同的非分类涡流状态。我们为这种涡旋模式提供了完整的分叉图，并表明，由于它们具有不同的能量，因此可以通过具有特定频率和空间构型的连贯的泵梁选择性地激发它们。在高泵浦强度下，极性 - 帕利顿相互作用产生了不同的涡旋共振的耦合，并实现了双旋转状态。
We model generation of vortex modes in exciton-polariton condensates in semiconductor micropillars, arranged into a hexagonal ring molecule, in the presence of TE-TM splitting. This splitting lifts the degeneracy of azimuthally modulated vortex modes with opposite topological charges supported by this structure, so that a number of non-degenerate vortex states characterized by different combinations of topological charges in two polarization components appears. We present a full bifurcation picture for such vortex modes and show that because they have different energies, they can be selectively excited by coherent pump beams with specific frequencies and spatial configurations. At high pumping intensity, polariton-polariton interactions give rise to the coupling of different vortex resonances and a bistable regime is achieved.
