Vortex solitons in the (2+1)-dimensional nonlinear Schrodinger equation with variable diffraction and nonlinearity coefficients Academic Article uri icon

abstract

  • Using Hirota's bilinear method, we determine approximate analytical localized solutions of the (2 + 1)-dimensional nonlinear Schrdinger equation with variable diffraction and nonlinearity coefficients. Our results indicate that a new family of vortices can be formed in the Kerr nonlinear media in the cylindrical geometry. Variable diffraction and nonlinearity coefficients allow utilization of the soliton management method. We present solitary solutions for two types of distributed coefficients: trigonometric and exponential. It is demonstrated that the soliton profiles found are structurally stable, but slowly expanding with propagation. 2013 The Royal Swedish Academy of Sciences.
