2015): The quadratic electro-optical effect in ferroelectric liquid crystal helical nanostructures: role of the driving voltage shape, Liquid Crystals,Recently it was shown that in deformed helix ferroelectric (DHF) structure, the electrically controlled birefringence Δn E of chiral smectic C* phase with subwavelength helix pitch (Δn E is known to be proportional to the square of the electric field E) depends on the cell thickness and on the frequency of applied voltage, given as a Step function of the time. The purpose of the present work is to investigate whether this quadratic effect depends also on the voltage function shape, comparing the electrically controlled birefringence Δn E and the Kerr constant in DHF cells with different thickness, driven by STAIR and Step voltage functions.

“…The helix-free FLC layer structure is formed due to the chiral components with opposite signs of opticity and identical signs of spontaneous polarization P s . 9 When its magnitude exceeds 50 nC/cm 2 , the spatial inhomogeneous distribution of P s (polarization fluctuations) arises along the direction, which is orthogonal to the smectic layers. This results in a smaller influence of the depolarization field directed opposite to the polarization, and the periodic modulation along the same direction of the azimuth angle ϕ of the director orientation [ Fig.…”

Abstract— Three types of light‐scattering effects distinguished by physical mechanisms were studied in detail in monomeric ferroelectric liquid‐crystal (FLC) compositions at different boundary conditions and electrical pulse regimes. The total time of the scattering switching on and switching off is less than 150, 250, and 500 μsec at ±50 V for different scattering types in helix and non‐helix FLCs. They are quite fast, and FLC cells are quite transparent and were used in a stack of 30–100 light‐scattering shutters for a volumetric screen of a 3‐D display.
