The very high birefringence of liquid crystals makes them attractive for photorefractive
applications. However, the drawbacks of using liquid crystals as photorefractives include a …

We report on the photorefractive properties of liquid crystals sandwiched between windows
of cerium doped strontium barium niobate (Ce: SBN). This adaptable design has been used …

Organic hybrids, comprising polymers and liquid crystals, have been explored for
photorefractive beam coupling and diffractive applications for almost two decades. The work …

▪ Abstract A review of the field of photorefractive liquid crystals is presented. The first reports
of photorefractive liquid crystals occurred in 1994, and the performance of these materials …

Photorefractive liquid crystals represent the newest class of photorefractive materials. The
low electric fields required for reorienting liquid crystals, combined with their high …

This review article presents the concept of photorefractive beam coupling in hybrid
photorefractive cells comprising a liquid crystal layer adjacent to inorganic photorefractive …

The gain characteristics of liquid crystal photorefractive cells doped with ferroelectric
nanoparticles has been measured. The liquid crystal two beam coupling gain is found to …

Highly birefringent liquid crystals are attractive for photorefractive applications but device
operation, usually restricted to the Raman-Nath regime, can be degraded by small phase …

This paper reviews our recent work on the photorefractive effect in liquid crystalline
materials. The photorefractive effect is defined as the optical modulation of the refractive …

Refractive index grating recording is achieved in the infrared in a nematic liquid crystal
placed between semiconductor CdTe substrates. Light-induced space-charge field created …
