| (a) Diffraction coefficient β ( z ), the profile coefficient f ( z ) and the nonlinear parameter χ ( z ) change along propagation direction; (b) the central positions, the phase offset, the frequency shift, and the phase-front curvature along propagation direction; (c) self-similar propagation dynamics of the vortex with loss g 0 = −0.01 for the diffraction decreasing waveguide. The initial values are given by Eq. ( 12 ) with an added 5% white noise. Other conditions and parameters are the same as Fig. 1 . |
