The importance of electrochromic effects in the ellipsometric determination of the electro-optic coefficient of poled polymer films is discussed. A relation between electrochromism and the complex electro-optic coefficient is proposed. The dispersion of the electro-optic coefficient for the charge-transfer molecules is shown to follow the simple two-level model.
