Abstract
The third-order nonlinear optical properties of a series of copoly(2,3,5,6-tetrafluoro-1,4-phenylenevinyl-ene-2,5-dioctyloxy-1,4-phenylenevinylene) that contain variable ratios of two differently substituted monomers have been studied in chloroform solutions at by the picosecond Z-scan technique. Nonlinear refractive index of the samples investigated has been found to be negative, and a strong dependence of its magnitude on the copolymer’s composition has been observed. The highest third-order nonlinear optical susceptibility, , was measured for a copolymer obtained by reaction of equimolar quantitites of the parent monomers.
