Abstract： The Photorefractive properties of PVK-based polymeric composites
doped with three liquid crystals, 4OCB (4-pertyloxy-4'-cyanobiphenyl ), 5OCB (4-pentyloxy-4'-cyanobiphenyl ), 8OCB (4-octyloxy-4'-cyanobiphenyl ) were investigated by using the two-beam coupling experiment at 633 nm. Gain coefficient over 34 cm -1 at an applied field of 60V/μm was observed. Among the three materials, the 8OCB-doped composite demonstrated a stronger orientational effect and the influence on charge field became apparent.
