研究了宇称时间(PT)对称势中的非线性对束流动力学的影响。我们证明了在光学PT合成晶格中可以存在一维和二维的非线性自陷模式。这些孤子在很宽的势参数范围内是稳定的。文中还研究了这些复孤子中的横向功率流。
We investigate the effect of nonlinearity on beam dynamics in parity-time (PT) symmetric potentials. We show that a novel class of one- and two-dimensional nonlinear self-trapped modes can exist in optical PT synthetic lattices. These solitons are shown to be stable over a wide range of potential parameters. The transverse power flow within these complex solitons is also examined.
