The effect of chromophores concentration on the nonlinear optical activity of methacrylic copolymers with azochromophores in the side chain

Abstract

© Published under licence by IOP Publishing Ltd. Quadratic nonlinear-optical characteristics of thin films based on methacrylic copolymers with of chromophore-containing monomers incorporated at various concentrations are measured by Second Harmonic Generation technique. Optimal chromophores content is obtained to be about 17 mol%, rather high values of nonlinear-optical coefficient, d33, up to 60 pm/V, are determined.
