Abstract
We report an experimental observation of the photorefractive effect in a new polymericsystem in which a nonlinear organic polymer was doped with a photosensitizer, borondiketonate (BDK), and a hole transport agent, tri‐p‐tolylamine (TTA). The photoconductivity and the electro‐optic effect have been studied. The process of grating formation with the applied field is presented. A strong electric field dependence of the diffraction coefficient has been observed.Keywords
