Dark and singular optical solitons in birefringent fibers with Kundu–Eckhaus equation by undetermined coefficients.

Abstract This paper retrieves dark and singular optical solitons in birefringent fibers that is modeled by Kundu–Eckhaus equation. The most fundamental principle of undetermined coefficients is the extraction algorithm applied to the model. These solitons appear with integrability criteria that are also presented.
