title: Description of the photorefractive response in polymers.
abstract: We employ a phenomenological approach to minimizing the assumptions underlying light-induced charge transport in polymers and expressing the steady-state photorefractive response of polymers through measurable medium characteristics. The relations obtained are shown to be useful for analysis of experimental data and theoretical predictions. The status of the phenomenological approach and its relationship with the known microscopic models are discussed.
