摘要

The influence of the glass-transition temperature T↓(g) 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-T↓(g) regime, composites of different chromophore content respond similarly quickly (200-500 ms), whereas significant differences occur for T↓(g)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.#1998 Optical Society of America OCIS codes: 090.0090, 260.0260, 160.5320, 160.4676, 160.5470.
