An exact solution is found for the Maxwell equations, which corresponds to a nonlinear surface Η wave when one of the contiguous dielectric media is optically uniaxial and has a diagonal dielectric constant tensor that depends on the amplitude of the field €#(ω,\Ε |2), en = €22 — *oM + ai\E\ 12 + \Ei\2)> езз = €(ω)>
