Abstract

Starting from a simple physical model, we propose a new scheme for increasing the fast nonlinear refractive response while decreasing linear and nonlinear absorptions in classical push- pull molecules. This effect is due to the reduction of their donor group strength of classical push-pull molecules. It is confirmed by multi-channel Z-scan measurements and by semi- empirical computations as well. Then, we have functionalized a copolymer, poly(maleic anhydride-co-octadecene), with these chromophores and measured its nonlinear refraction and absorption with respect to the chromophore nature.
