Diffractive gratings with period varied by an electric field are developed using a cholesteric
liquid crystal confined between two transparent electrodes with unidirectionally treated …

Electrically switchable diffractive gratings based on cholesteric liquid crystals are suggested.
An electric field switches the cholesteric cell between three states: two with a uniform in …

We study the phase diagram of director structures in cholesteric liquid crystals of negative
dielectric anisotropy in homeotropic cells of thickness d which is smaller than the cholesteric …

Patterned alignment layers have been created through an approach using polarization
holography and a photopolymerizable alignment layer. This technique enables continuously …

The dynamic pattern formation and the beam-steering characteristics of cholesteric gratings
were studied. Films with a planar cholesteric texture and various thickness to pitch length …

Smart windows and many other applications require synchronous or alternating facile
electric switching of transmitted light intensity in visible and near infrared spectral ranges …

It is known that the applying of the alternating electric field to a planar texture of cholesterics,
at the certain ratio between the LC cell thickness d and the cholesterical helix pitch P, can …

We demonstrate a fast-switching liquid-crystal mode with polymer-sustained twisted vertical
alignment. By optimizing the polymerization condition, a polymer microstructure with …

A wedge cell made of homeotropically treated glass plates is filled with a chirally doped
nematic liquid crystal. When a sufficiently large magnetic field is applied in the cell plane, a …
