  ABSTRACT: The purpose of this work is to study the nonlinear propagation of coupled pulses within birefringent optical fibers. To achieve this, an effective analytical technique using iB-function was applied. With this approach, we decoupled the nonlinear partial differential equations governing the wave propagation and solved them to obtain prototype solutions likely to propagate in the medium. A Mathlab program was then developed to validate the behavior of the propagated waves and analyze the resulting curves. The results revealed distinct complex phenomena such as stable propagation of coupled dark-bright vector soliton, energy exchange between the components during propagation to severe pulse broadening and conditions leading to group velocity walk-off. These findings provided a deeper insight into light propagation, improving its application for advanced optical communication systems and fiber-based devices.
