Spectral properties of photonic liquid crystal fibers

摘要

Microstructured photonic crystal fibers have an ability to modify their spectral properties when different materials are inserted into the holes. This paper presents our latest experimental results on spectral properties of photonic crystal fibers infiltrated with liquid crystals. Three different types of photonic crystal fibers host-structures were filled with nematic liquid crystals. The structures consisted of multi-core, isotropic or highly birefringent photonic crystal fibers. The nematic liquid crystals mixtures used as guest materials are characterized by either extremely low or medium material birefringence. This paper demonstrates a prototype multi-core photonic liquid crystal fiber showing strong influence of fluctuations in the fiber's dimensions on the selective propagation bands. The paper discusses the influence of temperature and of external electric field on the spectral properties of the photonic liquid crystal fibers and reports the latest experimental results with highly birefringent Blazephotonicsphotonic crystal fibers also filled with the nematic liquid crystal.
