In this paper, the (2 + 1)-dimensional coupled higher-order nonlinear Schrödinger equations are under investigation. The mixed-type vector solitons are derived via Hirota method. The interactions are analyzed graphically mainly on x–t and x–y planes. Moreover, a high intensity pulse, combined solitary waves and bound state solitons are discovered during the interactions. These results are available in optical fiber communication systems.

光纤中（2 +1）维耦合高阶非线性Schrödinger方程的混合型矢量孤子

本文研究了（2 +1）维耦合高阶非线性Schrödinger方程。混合型矢量孤子是通过Hirota方法导出的。交互作用主要在x – t和x – y平面上进行图形分析。此外，在相互作用过程中发现了高强度脉冲，孤立孤波和束缚态孤子。这些结果在光纤通信系统中可用。
