Optical solitons and stability analysis with spatio-temporal dispersion in Kerr and quadric-cubic nonlinear media.

Abstract In this work, we investigate the optical solitons to the nonlinear Schrödinger equation (NLSE) with spatio-temporal dispersion (STD) arising in ferromagnetic materials and optical fiber. The integration technique adopted is the Sine–Gordon expansion method (SGEM). In addition, the stability analysis of the model is performed. [ABSTRACT FROM AUTHOR]
