Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

We present a comprehensive analysis of the evolution of a grating envelope, in both
transmission and reflection geometry, during the erasure process in various readout …

We explore theoretically and experimentally how applying an electric field to a
photorefractive crystal affects the recording and the readout of a hologram. We present a …

We report what we believe to be the first observation of photorefractive gratings in lead
barium niobate (Pb_1-xBa_xNb_2O_6; PBN).? A diffraction efficiency of 9% and a beam …

For the first time to our knowledge, we demonstrate the use of self-enhanced diffraction to
optically restore weak dynamic volume holograms. This restoration process is achieved …

We consider the possibility of restoration and/or enhancement of decaying holograms in
photorefractive media by using a simple optical readout in conjunction with a phase …

We present an efficient photorefractive volume hologram recording technique with a pulsed
signal beam and continuous reference-beam illumination. The grating envelope can be …

Holographic data storage is a potential next–generation storage technology that offers both
high storage density and fast readout rate. In this article, I discuss the physical origin of these …

In a photorefractive Bi 12 SiO 20 crystal with high applied electric ac field of square-wave
shape a fast two-wave coupling response (less than 1 s) and a slow hologram readout …

Photorefractive properties of a 0.05-wt.% Ce_2O_3-doped Pb_0. 5Ba_0. 5Nb_2O_6 crystal
are investigated at visible wavelengths. Compared with the performance of the undoped …
