综述了近年来观察到的向列型液晶光学诱导折射率变化的机制，以及它们在新型光学限制和图像处理中的应用，并对它们的应用潜力进行了评估。我们还研究了向列液晶在近红外通信光谱区域[1.55µm]的光学非线性。在微米厚的薄膜中，用毫瓦激光功率可以产生几个π的相位调制。
The mechanisms for recently observed optically induced refractive index changes in nematic liquid crystals, and their use in novel optical limiting and image processing are reviewed, along with an assessment of their potentials for applications. We have also studied the optical nonlinearities of nematic liquid crystals in the near IR communication spectral region [1.55 µm]. Phase modulation of several π's can be generated with mW laser power in micron thick films.
