Nonlinear Surface Polaritons
Abstract
Among the highlights of the research conducted with the support of this grant are the first exact solutions for the dispersion curves of p- polarized nonlinear surface polaritons, on a nonlinear dielectric characterized by a Kerr-like dielectric constant; the first deviation of surface polariton (envelope) solitons associated with nonlinear guided electromagnetic waves; studies of the guiding of linear, p-polarized surface polaritons by the change in the index of refraction on a nonlinear dielectric medium caused by an intense, s-polarized surface polariton. The explanation for the k-gaps (as opposed to w-gaps) observed in some dispersion curves of surface polaritons on metallic gratings as determined by reflectivity measurements; and contributions to the theory of the stability of nonlinear surface electromagnetic waves. In addition, nonlinear surface and guided electromagnetic waves are studied on non- Kerr-like nonlinear dielectric media; the existence and properties of nonlinear guided electromagnetic waves are investigated in layered media consisting of alternating layers of linear and nonlinear dielectric media; a disordered surface can lead to the localization of a surface acoustic wave -- this appears to be the first demonstration of this effect; and evidence is provided for the existence of nonstationary, nonlinear guided electromagnetic waves.
