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.
