Liquid Crystal (LC) molecules orientation in Photonic Liquid Crystal Fibers (PLCFs) has crucial impact on their optical properties. There are many techniques used for LC molecules orientation control, but most of them are not suitable for application in microstructured fibers, which holes have diameters in the order of one micron. It seems that the only method that could be applied in PLCFs is using of thin photopolymer layers, in which surface anisotropy can be induced in the way of photochemical reactions. In this work experimental results of photoinduced molecular alignment in PLCF with thin polyvinylcinnamate (PVCi) film irradiated with linearly polarized ultraviolet light.
