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

A new class of photorefractive polymeric materials is described on the basis of inert polymer
binders doped with a single small molecule species which has the dual function of providing …

We investigate in detail the grating properties of a recently discovered organic
photorefractive polymer as a function of electric field by using two-beam coupling. Using an …

A new charge-transport model assuming one center in three different valence states is
discussed for explanation of the photorefractive effect. Quantitative description of …

A series of cobalt-doped barium titanate (BaTiO_3) crystals were grown; these crystals have
the highest beam-coupling gain reported to date, 7.9 cm^− 1, measured by using the …

The photorefractive properties of Sn2P2S6 crystals in the wavelength range from 633to1064
nm are investigated. Conventional yellow and modified brown crystals with a variation of …

A model of the photorefractive effect is presented that includes a shallow-trap level (hole or
electron trap) as well as a species of deep traps with electron and hole excitation. It is shown …

We present a method to separate the effects of trap gratings and electro-optic gratings in
BaTiO_3 crystals, and we determine the true spatial shift between the electro-optic grating …
