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 …

The simplified band transport model of the photorefractive effect in which the material
responds linearly to local changes in light intensity modulation ratio (fringe contrast) is …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

The photorefractive band transport model is extended to include magnetic effects. The
Newtonian equation of motion for electrons in the conduction band under combined electric …

The transient behavior of the fundamental amplitude of the photorefractive space-charge
field is derived without restrictions within the band transport model. The two-wave mixing …

The band transport model describes charge statics and dynamics within photorefractive
materials. Here a steady-state solution is found for the setting in which an arbitrary optical …

We apply directly a perturbative expansion to the hopping model of Feinberg. The first three
harmonics of the space‐charge field are presented, considering the contributions from the …

A two-dimensional time-dependent analysis is presented to describe photorefractive
recording in a film with anisotropic transport parameters. The solution of the rate equations …

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 …

A two‐dimensional treatment suitable both for perpendicular (Pockels readout optical
modulators, etc.) and for parallel (image amplifiers, etc.) photorefractive devices is …
