We report measurements of the third-order nonlinear optical properties of a newly synthesized thiophenebased copolymer. The nonlinear transmission measurements were performed on the copolymer dissolved in tetrahydrofuran by employing the single beam Z-scan technique. Q-switched laser output at 532-nm wavelength was used for this purpose. The nonlinear absorption coefficient, b, nonlinear refractive index, n 2 , and the real and imaginary parts of third-order susceptibility, v (3) , were, 18.93 cm/GW, 3.037 3 10 À17 m 2 /W (À1.022 3 10 À10 esu), 1.512 3 10 À20 m 2 /V 2 (À1.080 3 10 À12 esu) and 0.399 3 10 À20 m 2 /V 2 (0.285 3 10 À12 esu), respectively. The excited state absorption crosssection r exc , was found to be larger than the ground state absorption crosssection r g , indicating reverse saturable absorption (RSA) in the copolymer sample. The copolymer exhibits an optical power limiting threshold of about 120 lJ and saturated output of less than 80 lJ. Hence, the copolymer seems to be a promising material for photonic device applications.

The current status of organic low-molecular weight and polymeric materials for third-order nonlinear optics is reviewed. The importance of organic materials lies in their promise of large nonlinear optical figure of merit, high optical damage thresholds, ultrafast optical responses, architectural flexibility, and ease of fabrication. Organic materials exhibiting interesting third-order nonlinear optical properties are discussed to illustrate the importance of structure-property correlations. Results on emerging organic materials that include liquids, dyes, fullerenes, charge-transfer complexes, n-conjugated polymers, dye-grafted polymers, organometallic compounds, composites, and liquid crystals are presented. Organic nonlinear optical materials seem promising for a wide range of applications and their potential for integrated optics should be further explored.
