Optical solitons in birefringent fibers for Lakshmanan-Porsezian-Daniel model using exp(−ϕ(ξ))-expansion method

This paper studies optical solitons in birefringent fibers by the aid of exp-function approach. The model that is analyzed is Lakshmanan-Porsezian-Daniel equation which is first written in two-component form for vector solitons. The integrability criteria are also presented in the paper.
