摘要 数值研究了克尔双周期宇称一时间(Parity-time,PT)对称光晶格中能存在的空间光孤子,通过平面波展开法详细研究了此光晶格的带隙结构并获得其相变点。数值研究了此光晶格中能存在的空间光孤子及其传播稳定性,数值结果显示位于不同周期波导上的空间光孤子其稳定性区间不同。 Spatial solitons were numerically studied in Kerr dual-periodic parity-time(PT) symmetric optical lattices. The bandgap structures of this optical lattices were obtained by using plane wave expansion method, and the phase transition point was obtained at the same time. The existence and stability of the spatial solitons were numerically studied in this optical lattices. The results showed that the stable range of the solitons located on different period waveguide is different.
