Cubic-quartic optical solitons in birefringent fibers with four forms of nonlinear refractive index by exp-function expansion

Abstract

This paper applies exp-function expansion algorithm to secure to cubic-quartic dark and singular optical solitons in birefringent fibers that are studied with four forms of nonlinear refractive index. These solitons are listed along with their existence criteria and are also classified.
