Dispersive optical solitons in birefringent fibers with Schrodinger-Hirota equation

This paper obtains exact bright, dark and singular dispersive optical solitons in birefringent fibers in presence of several perturbation terms. The governing coupled Schrodinger-Hirota equation is integrated to extract these soliton solutions. The method of undetermined coefficients is applied to retrieve these soliton solutions. Constraint conditions naturally emerge for these solitons to exist.
