Photonic liquid crystal fibers for electric field and hydrostatic pressure sensing [7004-166]

چکیده
Photonic Crystal Fibers, optical fibers with regular structure of micro-holes running along the axial direction, have ability to change their optical properties through inserting different materials into their holes. The paper presents our latest experimental results of the influence of external electric field and hydrostatic pressure on propagation properties of the photonic crystal fibers infiltrated with liquid crystals clearly indicating great potential for electric field and hydrostatic pressure sensing applications. Operating range of both electric field and hydrostatic pressure sensors can be tailored by different combination of a host photonic crystal fiber and a liquid crystal used for infiltration. Moreover, by changing the operating wavelength different sensor responses can be obtained.
