The electronic tunability of ferroelectric liquid crystal filled photonic crystal fibers is experimentally demonstrated in the wavelength range of 1500 nm - 1600 nm. The tunability is achieved by applying electric field onto the ferroelectric liquid crystal infiltrated photonic crystal fiber. Tuning of the fiber propagation properties is achieved due to re-orientation of ferroelectric liquid crystal molecules on the application of the applied electric field. Such fibers could find applications in the fabrication of fast, low loss, cost effective and highly efficient in-fiber tunable devices to be used in the telecom wavelength range.
