Abstract
Third-harmonic generation measurements have been made on poly(2,5-thienylene vinylene) (PTV) thin films. The third-order optical susceptibility χ(3) was evaluated to be 3.2×10−11 esu at 1.85 μm wavelength. It was also revealed that in weakly iodine-doped PTV thin films, χ(3) was almost the same value as that of nondoped films. χ(3) at a shorter wavelength region was expected to be much higher than that obtained in this work due to the resonant effect.Keywords
