The ability to control light direction with tailored precision via facile means is long‐desired in
science and industry. With the advances in optics, a periodic structure called diffraction …

Recent progress in alignment modulation of azobenzene-containing liquid crystal systems
by photochemical reactions has been reviewed by dividing the modulation methods into two …

Photoalignment possesses significant advantages in comparison with the usual
'rubbing'treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact …

Two types of photomodulation of orientations of liquid crystals (LCs) are reviewed: 1) order–
disorder phase transitions of LCs induced by photochemical reactions of photochromic …

We report the first full numerical analysis of polarization gratings (PGs), and study their most
general properties and limits by using the finite-difference time-domain (FDTD) method. In …

A review of basic physical phenomena underlying the light-induced molecular reorientation
in nematic liquid crystals is presented. A detailed description of the mechanisms of direct …

We apply elastic continuum theory to model critical parameters influencing the free-energy
equilibrium configuration and the dynamic performance of a continuous and in-plane liquid …

The measurement of complete polarimetric parameters for a broad spectrum of wavelengths
is challenging because of the multi-dimensional nature of the data and the need to …

The basic mechanisms of photo-induced space charge field formation, director axis re-
orientation, and refractive index changes in fullerene C60-and dye-doped nematic liquid …

The ability of optical axis gratings (OAGs) to fully transfer the energy of an unpolarized
incident light beam into the±1st diffraction orders is explored below for development of a …
