We study localized surface waves at the interface between a linear dielectric and a photovoltaic–photorefractive (PP) crystal. These localized surface waves can be established provided that 0>δ−b>−α/20>δ−b>−α/2, where δδ is the guiding parameter, b is the propagation constant, and αα is the parameter related to the wavelength and the PP crystal. We show that when δ>0δ>0, the part of the energy concentrated in the PP crystal is always higher than that in the linear dielectric and that when δ<0δ<0, the part of the energy concentrated in the linear dielectric decreases with an increase in b . We find that the part of the energy concentrated in the linear dielectric for δ<0δ<0 is bigger than that for δ>0δ>0.
► Localized surface waves at the interface between two media are investigated.
► These localized surface waves can be established provided that 0>δ−b>−α/20>δ−b>−α/2.
► When δ>0δ>0, energy concentrated in PP crystal is higher than that in linear dielectric.
► When δ<0δ<0, energy concentrated in linear dielectric decreases with an increase in b .
► Energy concentrated in linear dielectric for δ<0δ<0 is bigger than that for δ>0δ>0.
