Exact results for the scattering of electromagnetic waves with a nonlinear film

Abstract

Exact analytical results for the scattering of a TE electromagnetic wave with a nonlinear thin film is derived. We assume that the incident wave is monochromatic, and that the film is nonabsorbing and has a Kerr-like optical nonlinearity. Among other things, the reflection coefficient is calculated exactly as a function of the incident intensity. Optical bistable and multistable behaviors are found. The phenomena of induced resonances and induced transparency are also discussed.
