Special soliton structures in the (2+1)-dimensional nonlinear Schrodinger equation with variable nonlinearity coefficient

Abstract

Abstract: A soliton solution to (2+1)-dimensional nonlinear Schrodinger equation with variable nonlinearity coefficients based on Hirota bilinear Method is gotten. Our results indicate that a new family of vortex solitons can be formed in the Kerr nonlinear media in the cylindrical symmetric geometry. These soliton profiles are stable, independent of propagation distance.

Key words: nonlinear optics, vortex soliton, Hirota bilinear method, nonlinear Schrodinger equation
