Abstract This paper established the second order ordinary differential equation of the propagation of the wave at the interface between a linear dielectric and a photorefractive crystal, researched the formation of the photorefractive nonlinear localized surface wave at the interface between linear dielectric and photorefractive medium with the method of numerical simulation and discussed the stability of the propagating of localized surface wave at the boundary. The results of the study show that the guiding parameter and propagation constant have effects on localized surface mode. As the augment of propagation constant. We did study on evolution of the propagation of localized surface wave which we get during researching by using the split step Fourier method; we found that the localized surface wave can propagate stably at the interface between linear dielectric and photorefractive crystal.

Key words： Nonlinear optics localized surface wave numerical simulation photorefractive crystal split step fourier method
