Birefringence measurement of polymer photonic crystal fibers infiltrated with liquid crystals by depolarization of light effect

Abstract

In the paper we estimate group birefringence of polymer photonic crystal fiber partially infiltrated with nematic liquid crystal 5CB. To calculate group birefringence we use a novel method proposed by our group based on depolarization phenomena of partially coherent light that takes place in anisotropic media such as liquid crystals and birefringent optical fibers. Taking into consideration spectral parameters of the light source and degree of polarization at the output of the fiber we calculated effective birefringence of the fiber partially infiltrated with liquid crystal. The results for empty polymer optical fiber were compared with the data provided by the manufacturer to confirm feasibility of applied method.
