Optical phase conjugation: principles, techniques, and applications
TL;DR: The backward phase conjugation (OPC) is a special relationship between two coherent optical beams propagating in opposite directions with reversed wave front and identical transverse amplitude distributions as mentioned in this paper.

Enhanced two-beam coupling in colloids of ferroelectric nanoparticles in liquid crystals
TL;DR: In this paper, the photorefraction in nematic liquid crystal (LC) doped with nanoferroelectric particles was investigated and the effect originated from an increased birefringence of the colloid and a stronger LC reorientation torque.
Journal ArticleDOI
Photorefractive liquid crystals.
TL;DR: A review of the field of photorefractive liquid crystals is presented in this paper, where the experiments and theoretical work that have been used to characterize these materials are reviewed and a review of composites of nonmesogenic polymers and liquid crystals are also discussed.

TL;DR: In this article, a surface-dependent lowering of the Friedericksz transition voltage in a planar cell upon light irradiation was found, and it is believed that this effect is due to a light-induced change in the near surface ion concentration in the presence of a dc field and a photosensitive surface.

Optical amplification with high gain in hybrid-polymer–liquid-crystal structures
TL;DR: In this paper, a very high net exponential gain Γ≈2600 cm−1 was observed in sandwich-type hybrid-polymer-liquid-crystal structures, which is a result of an energy exchange between two beams in a two-beam coupling experiment.

Coupled wave theory for thick hologram gratings
TL;DR: In this paper, a coupled wave analysis of the Bragg diffraction of light by thick hologram gratings is given, analogous to Phariseau's treatment of acoustic gratings and to the dynamical theory of X-ray diffraction.

Self-pumped, continuous-wave phase conjugator using internal reflection
TL;DR: Continuous-wave phase conjugation of an image-bearing beam is demonstrated using a single-domain crystal of BaTiO(3) and nothing else and has a phase-conjugate reflectivity of 30%.
Journal ArticleDOI
Molecular interpretation of the absorption-induced optical reorientation of nematic liquid crystals.
TL;DR: A molecular mechanism is proposed to explain the anomalous optical reorientation observed in nematic guest-host systems according to the interaction between the excited dye molecules and the nematic host.

Holographic grating formation in dye- and fullerene C(60)-doped nematic liquid-crystal film.
TL;DR: Transient and persistent holographic gratings have been observed in dye- and fullerene C(60)-doped nematic liquid-crystal films and the nature and time evolution of the underlying mechanisms, such as space-charge field production, flows, and dielectric- and conductivity-induced torques are examined.
