| 摘 要： | The （2＋1）-dimensional nonlinear SchrSdinger （NLS） equation with spatially inhomogeneous nonlinearities is investigated, which describes propagation of light in （2＋1）-dimensional nonlinear optical media with inhomogeneous nonlinearities. New types of optical modes and nonlinear effects in optical media are presented numerically. The results reveal that the regular split of beam can be obtained in （2＋1）-dimensional nonlinear optical media with inhomogeneous nonlinearities, by adjusting the guiding parameter. Furthermore, the stability of beam regular split is discussed numerically, and the results reveal that the beam regular split is stable to the finite initial perturbations.
