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