Abstract

The imaginary part of the third order nonlinear optical susceptibility is evaluated for several squaraine dyes to determine the characteristics of their excited states. Quadratic electroabsorption and linear absorption spectroscopy are used for this evaluaiton as well as to determine mechanisms responsible for the nonlinear optical properties of these dye-doped polymers. THe value of (chi) ⁽³) (in which we use an optical field to probe the effect of a static field) is of importance in evaluating the applicability of these thin-films dyes to all- optical devices. The nonlinear responses are compared to the three- and four-level models to help determine which models are most suitable for predicting nonlinear behavior.
