光纤通信是现代通信不可缺少的组成部分。本文研究了一个高阶耦合非线性薛定谔系统，它描述了两个电场在光纤中的同时传输。我们构造了混合相互作用下的N阶半有理孤子解和聚焦相互作用下的N阶呼吸子解，其中N为正整数.对于混合相互作用，我们给出了一阶和二阶暗-亮半有理孤子。对于聚焦相互作用，我们给出了一阶和二阶Y形呼吸子，一个分量含有反眼形呼吸子而另一个分量含有眼形呼吸子的线形呼吸子，以及每个分量由两个弯曲呼吸子组成的二阶呼吸子.
Optical-fiber communication is an indispensable part of the modern communication. In this letter, we study a higher-order coupled nonlinear Schrödinger system, which describes the simultaneous propagation of two electric fields in an optical fiber. We construct the N th-order dark–bright semi-rational soliton solutions for the mixed interactions, and the N th-order breather solutions for the focusing interactions, where N is a positive integer. For the mixed interactions, we show the first-and second-order dark–bright semi-rational solitons. For the focusing interactions, we present the first-and second-order Y-shaped breathers, and the line-shaped breather with one component possessing an anti-eye-shaped breather and the other component containing an eye-shaped breather, as well as the second-order breather with each component consisting of two curved breathers.
