Propagation characteristics of TE-waves guided by thin films bounded by nonlinear media

The behavior of nonlinear TE-waves guided by asymmetrical dielectric slab waveguides, having a generalized nonlinear substrate with a permittivity of the form /spl epsiv//spl sim/|E/spl I.oarr/|/sup /spl delta//, is analyzed. Using an analytical solution for the electromagnetic fields in this nonlinear media, the dispersion relations, electric field profiles, and cutoff frequencies are illustrated and discussed.<
