abstract

Photonic crystal fiber is glass or polymer fiber with array of microscopic air holes running along length of the fiber. Waveguide properties of such fiber can be controlled by introducing additional materials into the air holes. Liquid crystals (LC) are very suitable for that purpose because its refractive index can be easily tuned by electric field or temperature. Alignment of LC in photonic holes determines mostly the optical properties of the fiber. In this paper, we have developed the technique of photo-configurable alignment of LC in glass micro-tubes and in photonic crystal fiber. The order parameter of LC has been obtained from FTIR spectroscopy data and has demonstrated good alignment quality. Presented technique can be used as non-contact method of LC alignment in complex photonic crystal structure.
