摘要：
By reducing the Helmholtz equation in the form of complex vector, a new non-local Kerr media model is obtained. The solutions of vector multi-pole mode solitons and vortex solitons are derived and analyzed by using the variational method. Then, the spatial modulation nonlinearity and orbital azimuth modulation (OAM) of the model are studied by using the rotation equation. The results show that when the different modulated parameters are selected, the different rotation structures of vector multi-pole mode solitons or vortex solitons can be formed and it has a certain significance for the shape shaping and control of the soliton.
