摘要:

报道了在光纤激光器中非相干耦合暗矢量孤子捕获的实验观察。沿两个正交偏振方向的暗矢量孤子,虽然中心频率、能量和暗度相差很大,但由于非相干相互作用,仍然可以被同步捕获为群速度锁定的暗矢量孤子。数值模拟结果与实验结果吻合较好,在一定条件下证实了非相干耦合暗矢量孤子的存在。

英文摘要:

We report on the experimental observation of incoherently coupled dark vector soliton trapping in a fiber laser. Dark vector solitons along the two orthogonal polarization directions though with large difference in central frequency, energy and darkness could be still synchronously trapped as a group velocity locked dark vector soliton in virtue of the incoherent interactions. Our numerical simulation could well rebirth the experimental observations and confirm the existence of incoherently coupled dark vector soliton under certain conditions.
