Optical solitons in birefringent fibers with Biswas-Arshed equation by sine-Gordon equation method

Abstract Optical solitons in birefringent fibers are obtained in this paper. The coupled system derived from the Biswas-Arshed equation for birefringent fibers is studied. The four-wave mixing terms are neglected. Dark soliton, singular soliton, bright soliton and combo singular soliton solutions are imparted by the sine-Gordon equation scheme.
