title: Localized surface waves at the interface between linear dielectric and biased centrosymmetric photorefractive crystals.
abstract: We study localized surface waves at the interface between linear dielectric and biased centrosymmetric photorefractive (CP) crystals. If the propagation constant b is fixed, the energy of localized surface waves increases with the order of localized surface waves. For low b values, the considerable part of the energy of localized surface waves is concentrated in the linear dielectric and decreases with an increase in b. For high b values, the part of the energy of localized surface waves concentrated in the nonlinear CP crystals is always higher than that in the linear dielectric and increases with b. The stability properties of these localized surface waves are also discussed in detail.
