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

We propose a matrix–matrix multiplication by using anisotropic self-diffraction in BaTiO_3.
The input matrices are carried by the two incident beams with special Bragg-matched …

A numerical approach has been developed for simulating the recording and erasure kinetics
in photorefractive materials for high modulation of the light-intensity pattern. The recording …

The time evolution of the charge carrier density, ionized donor density and space‐charge
field under a sinusoidal light pattern have been calculated by solving numerically the …

A general approach to photorefractive kinetics, based on the band-transport model, has
been developed for nonphotovoltaic materials in the diffusion regime. For small grating …

Thick holographic refractive index gratings are written in nominally pure and in iron doped
BaTiO 3 crystals. The phase shift between refractive index grating and light pattern is studied …

The process of high-gain image amplification in photorefractive crystals is investigated. We
show that in the regime of large energy transfer, the spatially nonuniform depletion of the …

Experimental data of the influence of light modulation amplitude m on the photorefractive
effect in Bi 12 SiO 20 (BSO) are reported. In these experiments charge diffusion was the …

The cross coupling of two mutually incoherent sources in photorefractive materials is
described. It is shown that when there are two mutually incoherent pump beams that are not …

The analytic expressions for the first three higher-order harmonics of the space-charge field
versus time are obtained by use of the hopping model of Feinberg [J. Appl. Phys. 51, 1297 …
