Article Synopsis
- The study explores how a plane wave interferes with localized waves using the coupled Fokas-Lenells equation, incorporating a four-wave mixing term.
- Significant findings include the creation of localized wave solutions through the linear superposition of plane and soliton waves, leading to various nonlinear interference patterns based on soliton parameters.
- The research could benefit fields like soliton control, all-optical switching, and optical computing through a systematic analysis of different interference conditions.

We investigate coupled nonlinear Schrödinger equations (NLSEs) with variable coefficients and gain. The coupled NLSE is a model equation for optical soliton propagation and their interaction in a multimode fiber medium or in a fiber array. By using Hirota's bilinear method, we obtain the bright-bright, dark-bright combinations of a one-soliton solution (1SS) and two-soliton solutions (2SS) for an n-coupled NLSE with variable coefficients and gain.
