Abstract
In this work, a two coupled nonlinear Schrodinger equation (CNLSE) which is applicable to high birefringence fibers is investigated. We operate a variety of ansatze to derive a variety of bright and dark optical envelope soliton solutions. Also, other solutions of distinct structures, periodic, exponential, and singular, are derived. This analysis shows the pertinent contribution of nonlinear terms to both pulse compression feature and nonlinear birefringence phenomena.
