Novel Method Of Electro-Optic Constant Measurement

A new convenient method is proposed to determine the electro-optic (EO) constants and relevant nonlinear susceptibilities. It was applied to polycarbonate films doped with 4-diethylamino-4'-nitrostilbene (DEANS). The real and imaginary parts of the third-order nonlinear susceptibility X(3) (-ω;ω,0,0) of the film with several pincentrations of DEANS were obtained in the visible region. The magnitude of relevant X(3) is proportional to the concentration of DEANS. The mechanism of the EO effect of these samples is discussed, in terms of the restricted orientational motion of doped molecules.
