Abstract :
The paper describes four different types of micro-electrodes systems for dynamic electric field sensing with photonic crystal fibers infiltrated with liquid crystals. The shortest switching time ~20 ms was achieved by using a flexible-flat-cable electrode system. A capillary system with four micro-electrodes (τ ~ 36 ms) appeared to be the most convenient to operate with photonic liquid crystal fibers. The capillary system was also theoretically analyzed and presented in this paper.
