Special soliton structures in (2+1)-dimensional nonlinear Schrdinger equation with variable nonlinearity coefficient
A soliton solution to (2+1)-dimensional nonlinear Schrdinger equation with variable nonlinearity coefficients based on Hirota bilinear method was obtained. The 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.
