Abstract
The influence of the glass-transition temperature Tg and the electro-optical chromophore content on the grating buildup dynamics in photorefractive polymer composites is investigated. The response times were found to be strongly dependent on both parameters. In the low-Tg regime, composites of different chromophore content respond similarly quickly (200–500 ms), whereas significant differences occur for Tg above the measurement (room) temperature. The composites with the highest chromophore content give the best steady-state performance; however, their response is much slower than that for those containing less chromophore.
