E. Mecher et al., Optimization of the recording scheme for fast holographic response in photorefractive polymers, SYNTH METAL, 102(1-3), 1999, pp. 993-996
The influence of the recording scheme on the dynamic performance of a photo
refractive polymer composite is investigated. In the low-T-g composite stud
ied here, the response time is at first limited by the formation of the pho
torefractive space-charge field and on a longer time scale by the orientati
on of the electrooptic chromophores. By in situ pre-poling the devices befo
re writing the hologram a substantial speed enhancement was achieved compar
ed with non-prepoled devices.
