The transmission of a polymer film doped with dye molecules is modulated by voltage-induced changes of the population in the center of a persistent spectral hole. It is demonstrated that the transmission versus voltage characteristic of the sample is adjustable to the requirements of the desired application by applying a selected time-dependent voltage during spectral hole burning. Various characteristic curves have been tailor made and used for modulation and pulse forming of laser beams.
