Optical investigation of photopolymer systems for microholographic storage

We investigate different classes of organic photosensitive materials in order to optimize the interaction between the material itself and a surrounding optoelectronic system. The focus of investigation is the application to microholographic data storage. Key issues are the dynamic material response, spatial resolution and photoresponse, spectral and temporal grating development, influence of the light intensity distribution, and impact of pre-exposure. The materials under investigation are cationic ring opening and free radical polymerization systems.
