Part of the Springer Series in Materials Science book series (SSMATERIALS, volume 240)


After a brief historical introduction about photorefractive materials, this chapter provides an extensive overview of the mathematical modeling of the photorefractive effect in organic compounds. The theories of charge photo-generation, transport and trapping, as well as chromophore orientation in the space-charge field are detailed. We then discuss the different molecular species providing the respective functionalities to the PR effect: electroconductive matrices, nonlinear chromophores, photo-sensitizers, and plasticizers, along with the recent developments in the search for more effective materials. Several electrode geometries for different types of devices are described before a section on material characterization. This later include measurement techniques of the molecular properties such as energy levels, photoconduction, and index change, followed by the holographic setups such as four-wave mixing and two-beam coupling, along with the theory to extract the important parameters out of the measured quantities.
