ON THE THEORY OF TE-POLARIZED WAVES GUIDED BY A NONLINEAR 3-LAYER STRUCTURE

TE-polarized electromagnetic waves guided by a three-layer structure c onsisting of a film surrounded by semi-infinite media (all media are c haracterized by a Kerr-like dielectric function) are investigated by e xpressing the solution of the field equations in terms of Weierstrass' elliptic functions. Evaluation leads to a universal dispersion relati on and its solutions and a universal expression for the power flow. Nu merical results are presented for the effective wave number as a funct ion of the intensity of the electric field at the lower surface of the nonlinear film, for various profiles of the field intensity, and for the power flow as a function of the effective wave number.
