摘要

两束相交光束照射具有螺旋聚合物网络的胆甾液晶。光折变衬底的空间电荷场迫使聚合物纤维移动并诱发定向光栅。光束在光栅内的耦合导致弱光束增益系数大于固体光折变晶体。

Two-beam Energy Exchange in a Hybrid Photorefractive Cholesteric Cell with a Helicoidal Polymer Network

Two intersecting light beams illuminate cholesteric liquid crystal with helicoidal polymer network. Space-charge field of photorefractive substrate forces polymer fibrils to move and induce director grating. Coupling of light beams within the grating leads to weak beam gain coefficient greater than in solid photorefractive crystals.
