The photorefractive effect is now firmly established as one of the highest-sensitivity
nonlinear optical effects, making it an attractive choice for use in many optical holographic …

We consider holographic optical data storage systems implemented with photorefractive
media. Our viewpoint emphasizes the close interaction between materials and device …

Two coherent light beams can couple in any absorbing material owing to a light-induced
modulation of the material's dielectric constant. In photorefractive crystals the coupling …

We report the direct recording of electron-based photorefractive hologram in nominally
undoped Bi 12 TiO 20 crystals using 780 nm wavelength light without pre-exposure or any …

The time evolution of space-charge field gratings in photorefractive media is derived for a
simple two-level electron–hole-transport model. At one level, charge transfer occurs by …

Principal and complementary space-charge gratings are formed in photorefractive bismuth
silicon oxide with use of 785-nm light. An electric field is optionally applied in the direction of …

We report the photoconductive properties and photorefractive grating response time of a
polymer mixture composed of 40-wt.% dissolved diethylamino-benzaldehyde diphenyl …

A two-center photorefractive model permitting all center-to-band transitions and electron-
hole charge transport unifies several models describing subsets of these transitions. Using …

The temperature dependence of the photorefractive effect in a polymer composite containing
poly (9-vinycarbazole), tricresyl phosphate, buckminsterfullerene, and 4-(N, N-diethylamino) …

We report observations of electric-field stabilization of gratings and grating competition in a
new photorefractive polymer mixture composed of 40 wt.% diethylamino-benzaldehyde …
