摘要：

By means of the Hirota bilinear method, we obtain the hollow ring-like soliton and dipole soliton solutions of the coupled nonlinear Schrodinger equation in the ()-dimensional inhomogeneous -symmetric nonlinear couplers. Based on these analytical solutions, we investigate the compression behaviors of hollow ring-like soliton and dipole soliton in a diffraction decreasing system with exponential profile.
