Light Reconfigurable Geometric Phase Optical Element with Multi-stable States
Xiao-Qian Wang, Alwin Ming-Wai Tam, Wei-Qiang Yang +9
We present the design methodology of a light reconfigurable geometric phase optical element with multi-stable diffraction efficiency states, enabled by a photoresponsive self-organ…
Enhanced Kerr effect in vertically aligned deformed helix ferroelectric liquid crystals
E. P. Pozhidaev, A. K. Srivastava, Alexei D. Kiselev +5
We disclose the vertically aligned deformed helix ferroelectric liquid crystal (VADHFLC) whose Kerr constant (~nm/V at ~nm) is one order of…
Orientational "Kerr effect" and phase modulation of light in deformed-helix ferroelectric liquid crystals with subwavelength pitch
Eugene P. Pozhidaev, Alexei D. Kiselev, Abhishek Kumar Srivastava +3
We study both theoretically and experimentally the electro-optical properties of vertically aligned deformed helix ferroelectric liquid crystals (VADHFLC) with subwavelength pitch…
Polarization gratings in the short-pitch approximation: electro-optics of deformed helix ferroelectric liquid crystals
Alexei D. Kiselev, Eugene P. Pozhidaev, Vladimir G. Chigrinov +1
Electro-optical properties of deformed helix ferroelectric liquid crystal (DHFLC) cells are studied by using a general theoretical approach to polarization gratings in which the tr…
Kinetics of photoinduced ordering in azo-dye films: two-state and diffusion models
Alexei D. Kiselev, Vladimir G. Chigrinov, Hoi-Sing Kwok
We study the kinetics of photoinduced ordering in the azo-dye SD1 photoaligning layers and present the results of modeling performed using two different phenomenological approaches…
Liquid crystal pretilt control by inhomogeneous surfaces
Jones T. K. Wan, Ophelia K. C. Tsui, Hoi-Sing Kwok +1
We consider the pretilt alignment of nematic liquid crystal (LC) on inhomogeneous surface patterns comprising patches of homeotropic or homogeneous alignment domains, with azimutha…
