Third-Order Nonlinear Optical Effects in Molecular and Polymeric Materials

Abstract

This review is aimed at seeking the participation of the chemical community in the exciting new field of nonlinear optics. Chemists and chemical engineers with backgrounds ranging from synthesis to theory can make valuable contributions in this field as it offers challenges both for fundamental and applied research. The article focuses specifically on third order nonlinear optical processes in molecular and polymeric materials. Basic concepts are briefly reviewed along with a discussion of some structural requirements for third order effects. Some widely used measurement techniques are presented. The current status of third-order nonlinear optical material is reviewed along with a discussion of the relevant fundamental and technological issues. The article concludes with a discussion of the important areas in which chemists and chemical engineers can make important contributions (1).
