TLDR
In this paper, the authors review recent theoretical progress in understanding physical processes of composite effects on enhanced third-order nonlinear optical responses of various kinds of the recently proposed non-linear optical materials, namely, colloidal nanocrystals with inhomogeneous metallodielectric particles or a graded-index host, metallic films with inhmogeneous microstructures adjusted by ion doping or temperature gradient, composites with compositional gradation or graded particles.About:

High-order optical nonlinearities in plasmonic nanocomposites—a review
Albert S. Reyna,Cid B. de Araújo +1 more
TL;DR: In this paper, a nonlinearity management procedure for high-order optical nonlinearities (HON) in metal-dielectric nanocomposites is presented. But the authors focus on the properties of metal nanoparticles and demonstrate that these plasmonic composites are versatile platforms for high order nonlinear optical studies.
