Abstract
We report measurement of χ3 in polythiophene and a homologous series of polycondensed thiophene-based polymers above and below the absorption edge using the folded-boxcar four-wave mixing technique. Above gap the nonlinear coefficient χ3 was found to be one of the largest and fastest in a polymer.Keywords
