The development of real-time devices for the manipulation of two-dimensional time-varying
coherent wavefronts is of major interest for optical processing applications. It was …

The mechanism of the photorefractive grating recording and erasure in electrooptic crystals
is discussed in detail in TAP61. We will thus restrict this section to the presentation of the …

We have analytically solved the problem of N mutually incoherent pairs of beams in
photorefractive media, each pair of which shares a common grating. The results are applied …

After a rapid introduction that indicates the main reasons for the renewal of interest for
photorefractive holographic memories, we will first present and compare both the coding …

The advances of photorefractive optics have demonstrated many useful and practical
applications, which include the development of photorefractive optic devices for computer …

The ability of photorefractive crystals to holographically record an optical image in real time
allows one to use them in a variety of optical information processing systems. A number of …

The dynamics of a composite grating that consists of an original grating and a newly
superimposed grating are investigated for memory applications by solution of coupled-wave …

The physics of the photorefractive effect and the unique nonlinear optical properties of
photorefractive crystals are described. A survey of the optical applications of the …

The photorefractive effect is a phenomenon in which the local index of refraction is changed
by the spatial variation of the light intensity. Such an effect was first discovered in 1966. The …
