The response of a photorefractive phase conjugator to time-varying signals is examined.
Maxwell's equations are coupled to the material equations followed by linearization using a …

We report a theoretical model for a photorefractive running hologram in bulk-absorbing
materials in the presence of self-diffraction and use this model to analyze experiments for …

The two-wave mixing effective gain in cubic optically active photorefractive crystals is
studied as a function of the holographic grating vector orientation, polarization of interacting …

The photorefractive grating formation dynamics were modeled numerically for bismuth
silicon oxide under conditions of stationary recording with a dc applied electric field. These …

The frequency dependence of the photorefractive effect is considered. The frequencies can
be applied by introducing a temporal phase shift in one of the beams in a two-wave mixing …

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 …

A photorefractive frequency converter and phase-sensitive detector is proposed and
demonstrated. Dynamic photorefractive theory is used to examine device characteristics for …

We use holographic techniques for the investigation of strongly oxidized LiNbO 3: Fe
crystals with small Fe 2+ concentrations and compare the results with theoretical predictions …

Undoped single crystals of the organic electro-optic material 4′-nitrobenzylidene-3-
acetamino-4-methoxyaniline were found to show photorefractive effects owing to light …

In general, the application of an electric field to a photorefractive material with optical activity
results in a change in the effective electro-optic coefficient, r eff, which, in turn, alters the …
