The nonreciprocal phase shift of TM waves guided by the linear thin film sandwiched between magnetooptic semi-infinite substrate and nonlinear Kerr-type semi-infinite cladding has been investigated theoretically and numerically. With the help of the conservation energy law for TM modes in nonlinear waveguide the dispersion relation without a knowledge of the nonlinear field profile has been derived. The dependence of the nonreciprocal behaviour of the guided waves in terms of the local intensity at the film-nonlinear cladding boundary is discussed. Introducing a nonlinear material into magnetooptic waveguide structure leads to interesting applications for a new class of integrated devices which combine magnetooptic and nonlinear effects.
