Recording of a diffraction grating in a photopolymerizable material in the presence of a liquid crystal is studied theoretically in terms of the polymerization equation with allowance for diffusion. A model explaining the occurrence of recording dela

The combination of two noncoherent copropagating beams enables us to study the roles of the electromagnetic field symmetry and angular momentum in optically induced Fr\'eedericksz transition. The particular choice of the interaction geometry allows o

We show that the character of the Fr\'eedericksz transition is significantly changed when circular and helicoidal standing electromagnetic fields are used for excitation. Optical control, such as selective enhancement or suppression, of the collectiv

Light-induced molecular orientation switching and large intrinsichysteresis in a homeotropic cell of nematic liquid crystals areobtained. Both the switching threshold and the hysteresis width areeffectively controlled by the elliptical symmetry of a

Dynamic holography and polarimetric techniques are used to study the photoisomerization kinetics of D2 bisazo dye and the excitation transfer from dye to nematic liquid crystal host. As a result of this transfer, transient modulation of the orientati

A new approach for producing dynamic amplitude holograms in liquid crystals is proposed. A steady-state amplification of a probe wave should occur at gratings of the orientation of the molecules of a nematic liquid crystal when an orthogonally polari

Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals.
Chalcogenide glasses (ChG) have been shown to be very promising candidates for optical information storage and infrared communication systems [1]. The high photosensitivity of these materials in the visible (near bandgap for ChG) spectral band allows
