We theoretically analyze the waveguide regime of light propagation in a cylindrical pore of a polymer matrix filled with liquid crystals assuming that the effective radial optical anisotropy is biaxial. From numerical analysis of the dispersion relations, the waveguide modes are found to be sensitive to the field-induced changes of the anisotropy. The electrooptic properties of the polymer porous polyethylene terephthalate (PET) films filled with the nematic liquid crystal 5CB are studied experimentally and the experimental results are compared with the results of the theoretical investigation.

光在填充向列液晶的聚合物多孔膜中的波导传播

假设有效径向光学各向异性是双轴的，我们从理论上分析了光在填充有液晶的聚合物基质的圆柱形孔中传播的波导机制。从色散关系的数值分析中，发现波导模式对场引起的各向异性变化很敏感。实验研究了填充有向列液晶5CB的聚合物多孔聚对苯二甲酸乙二醇酯（PET）薄膜的电光性能，并将实验结果与理论研究结果进行了比较。
