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

We study the possibility of self-trapping of an optical beam in a photorefractive medium
under the combined influence of diffraction and self-scattering (two-wave mixing) of its …

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

The photorefractive properties of semi-insulating AlGaAs–GaAs multiple quantum wells are
described for the transverse Franz–Keldysh geometry with the electric field in the plane of …

A simple method to trap and manipulate metallic micro/nano-particles on the surface of
photorefractive crystals is proposed. After inducing inhomogeneous charge density and …

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 present data showing a nonlinear photorefractive response at high modulation depths in
a Bi_12TiO_20 sample when applied ac fields are used. The data are interpreted by means …

Single crystals of Bi2TeO5, both undoped and doped with transition‐metal‐ion dopants,
were grown with high optical quality. Continuous‐wave four‐wave‐mixing experiments on …

The diffraction from a thick photorefractive hologram is shown to be angular dependent,
which originates mainly from the angle-dependent effective electro-optic coefficient of a …

The nonlinear differential equations describing the response of photorefractive material to a
moving sinusoidal intensity pattern that permits large modulation depth are solved by a …
