Phase mismatches with regard to light of photorefractive gratings have been investigated for
arbitrary modulation depths of the illuminating pattern. The time evolution of the phases …

In this paper, we have applied a perturbation expanding method to the hopping model, and
studied the coupling effect of modulation depth between two photorefractive phase gratings …

Double gratings form in anisotropic photorefractive crystals when two plane waves
intersecting inside the crystal have both extraordinary and ordinary wave components. The …

A finite difference method is used to analyze the behavior of photorefractive InP: Fe at high
fringe contrast under externally apphed field. The evolution with increasing fringe contrast m …

In an extension of earlier work by Moharam et al.[J. Appl. Phys. 50, 5642 (1979)], we use a
perturbation scheme to obtain a higher-order expression for the steady-state photorefractive …

Based on a two-level model of optical transitions, the problem of positive and negative
feedback effects during simultaneous reading and writing of dynamic holograms in …

It is shown that a moving intensity grating in a photorefractive crystal with a sufficiently large
lifetimemobility product can give rise to an instability against excitation of weakly damped …

The phase shift between the pattern of light onto a photorefractive crystal and the resulting
hologram at the very beginning of the recording process in two-wave mixing is analyzed and …

The space-charge wave theory of photorefractive parametric amplification is presented. It
describes the amplification process in which a strong running holographic grating pumps …
