The paper analyzes polarization properties and presents the latest experimental results on polarization phenomena occurring in microstructrured photonic liquid crystal fibers (PLCFs) in which only selected micro holes or holes areas were filled with prototype nematic liquid crystal guest materials that are characterized by either extremely low (of the order ~ 0.05) or relatively high (of the order ~ 0.3) material birefringence. The photonic crystal fiber host structure was a commercially available highly birefringent PCF (Blazephotonics). The PLCFs under investigation have been powered by a tunable laser operating at infrared. Due to anisotropic properties of the microstructured PLCFs, switching between different guiding mechanisms as well as electrically and temperature-induced tuning of both light propagation and fiber birefringence has been demonstrated.
