The dynamics of a composite grating that consists of an original grating and a newly
superimposed grating are investigated for memory applications by solution of coupled-wave …

We introduce the concept of traveling grating envelopes to study the erasure dynamics in
bulk photorefractive media. This new technique provides considerable physical insight into …

We have analyzed the dynamics of the selective erasure process in photorefractive crystal.
The selective erasure process is much faster than the incoherent erasure process …

We examine simultaneous write–read of dynamic photorefractive gratings for arbitrary phase
shifts between index grating and intensity pattern. The nonlinear behavior of diffraction …

We have analytically solved the problem of N mutually incoherent pairs of beams in
photorefractive media, each pair of which shares a common grating. The results are applied …

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 …

We propose and demonstrate experimentally a new, phase-locked refreshment method for
reading out dynamic holographic photorefractive memories without destruction of the stored …

Growth-induced striations in photorefractive media constitute phase gratings that scatter
transmitted light and therefore degrade the quality of reconstructed images in holographic …

The effect of gray scale in writing-beam intensity on the recorded refractive-index modulation
is investigated by using both scheduled and incremental recording dynamics for volume …

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 …
