Cubic-quartic bright optical solitons with improved Adomian decomposition method.

Cubic-quartic soliton transmission having power law of nonlinearity refractive index. • Optical soliton solutions for the perturbed nonlinear Schrodinger's equation are revealed. • Quadratic-cubic nonlinearity is considered. • Bright optical solitons are retrieved by the help of the IADM. • The numerical results together with high level accuracy plots are exhibited. • The method proposed herein works with high degree of accuracy. This paper numerically retrieves cubic-quartic solitons having power law of nonlinearity refractive index. An improvement of the Adomian decomposition scheme is the adopted algorithm of this work. The results are displayed along with the established error analysis. [ABSTRACT FROM AUTHOR]
