Abstract

A new and simple spectroscopic method for the determination of the trap density in C₆₀-sensitized photorefractive polymers is presented. This method is compared with results obtained from traditional trap density measurements which involve two-wave mixing, and good correlation is observed. This technique is used to identify the inactive traps as the nonlinear optical chromophore. Also, composites with very low response times, high gain coefficients and low absorption are presented.
