Optical solitons in birefringent fibers with Kundu-Eckhaus equation

This paper employs two strategic integration algorithms to extract soliton solutions to Kundu-Eckhaus equation in the context of birefringent fibers. The two schemes are G′/G2-expansion approach and sine-cosine method. Bright, singular and dark-singular combo solitons are retrieved. With reversed constraint conditions, singular-periodic solutions also emerge, although they are not applicable to the photonics field.
