Nonlinear Optical Wave Equation for Micro- and Nano-Structured Media and Its Application.

摘要

A novel optical wave equation is developed for optical wave propagation and interaction in materials with intrinsic or induced macroscopic spatial inhomegeneity. It shows that the effect of spatial inhomogeneity is most pronounced for sizes of inhomogeneities on a sub-wavelength scale, that is in materials commonly referred to as nanophotonic materials. Respectively the new equation provides a rigorous theoretical template for emerging experimental activity worldwide in the area of linear and nonlinear nanophotonics.
