We study experimentally self-trapping of optical beams in photorefractive media and show
that the trapping is inherently asymmetric with respect to the two (transverse) trapping …

We report experimental results that demonstrate for the first time, to our knowledge, more
than 20 holograms stored and recalled with equal diffraction efficiency in photorefractive …

We report an analysis of the feedback circuit operation that produces fringe-locked
photorefractive running holograms. In agreement with theoretical expectations we …

We present a theoretical analysis of the stability of photorefractive spatial solitons along with
experimental results that show that the solitons are stable for small-scale perturbations but …

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

We study the behavior of light waves at an interface between linear and photorefractive
media, where the incident wave propagates from the linear side. We find bistable behavior …

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 …

The recording and replay of volume phase gratings in photorefractive crystals is investigated
for both transmission and reflection geometries. Differential equations are derived and …

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 …
