Abstract

Owing to their large third-order non-linearities and to their physico-chemical processability, conjugated polymers are thought as key materials for optical processing functions. The large effects are enhanced by resonances whose position and strength have thus to be precised. The recently developed Kerr-ellipsometry is a convenient technique^[1] as it permits separation of the real and imaginary parts of the non-linear pump-induced anisotropy.
