Abstract: We disclose the vertically aligned deformed helix ferroelectric liquid crystal (VADHFLC) whose Kerr constant (Kkerr ~144 nm/V2 at ¥ë = 543 nm) is one order of magnitude higher than any other value previously reported for liquid crystalline structures. Under certain conditions, the phase modulation with ellipticity less than 0:05 over the range of continuous and hysteresis free electric adjustment of the phase shift from zero to 2p have been obtained at sub-kilohertz frequency.
