摘要：

The standard model for photorefractivity, which was originally developed for inorganic photorefractive crystals, yields a relation between the pertinent parameters of photoconductivity and the holographic response time. We investigated a photorefractive guest host polymer with respect to these properties by photoconduction and holographic experiments. Our system consists of a photoconducting siloxane polymer, which is sensitized by trinitrofluorenone, and an azo chromophore as nonlinear optical moiety. We compare measurements of photoconduction and response time as a function of the external electric field and the incident Light intensity in order to test the applicability of the standard model to photorefractive polymers.
