Stable soliton propagation in a coupled (2+1) dimensional Ginzburg-Landau system

摘要： In this paper, a coupled (2+1)-dimensional variable coefficient Ginzburg-Landau equation is studied. By virtue of the modified Hirota bilinear method, the bright one-soliton solution of the equation is derived. Some phenomena of soliton propagation are analyzed by setting different values of the dispersion term. The influences of the corresponding parameters on solitons are also discussed. Results can enrich the soliton theory, and may be helpful in the manufacture of optical devices.
