This paper numerically addresses optical dromions and domain walls that are monitored by Kundu – Mukherjee – Naskar equation. The Kundu – Mukherjee – Naskar equation is considered because this model describes the propagation of soliton dynamics in optical fiber communication system. The scheme employed in this work is Laplace – Adomian decomposition type. The accuracy of the scheme is \(O(10^{-8})\) and the physical structure of the obtained solutions are shown by graphic illustration in order to give a better understanding on the dynamics of both optical dromions and domain walls.

用拉普拉斯—阿domian分解方案的昆都—穆克吉—纳斯卡方程计算光学色散和畴壁

本文用数值方法解决了由Kundu – Mukherjee – Naskar方程监测的光学漂移和畴壁。考虑了Kundu-Mukherjee-Naskar方程，因为该模型描述了光纤通信系统中孤子动力学的传播。在这项工作中采用的方案是拉普拉斯-阿domian分解类型。该方案的精度为\（O（10 ^ {-8}）\），并通过图形方式显示了所获得解决方案的物理结构，以使人们更好地理解光学漂移和畴壁的动力学。
