摘要
Via the similarity transformation method,we obtain an approximate vortex solution to the generalized(2+1)-dimensional nonlinear Schrödinger equation with space-dependent diffraction,nonlinearity and gain/loss coefficients.Under certain parametric conditions,we investigate the propagation dynamics of self-similar vortex solitons in optical media.
