It is shown that an interface between two dielectric media, where the lower-refractive-index material has a positive optical Kerr coefficient, can support a two-dimensional optical surface wave that propagates along the interface with a constant shape and intensity. Analytical expressions describing the wave are derived, and the characteristics of the wave are discussed.
