In this paper we review four photorefractive devices which have been investigated and
further developed in our laboratories. We discuss the fundamental behavior of a …

Pattern formation and self phase conjugation are observed simultaneously in photorefractive
potassium niobate. The effects have been modelled assuming the presence of reflection …

This thesis is an experimental and theoretical investigation of nonlinear optics in photo-
refractive crystals, and applications thereof. Coherent light is used to induce nonlinear …

We demonstrate that the negative amplitude gain in a photorefractive two-wave-mixing
experiment under applied electric field measurably reduces the characteristic instability of …

The exchange of informations at high data rates between optoelectronic transducers is an
important task encountered in all advanced architectures of high capacity parallel optical …

A review is given of the present status of the non-linear optical materials and devices, and
their applications for optical signal processing and computing. The primary motivation …

A recently predicted resonant effect for the enhancement of two-wave mixing in
photorefractive materials is investigated. The resonance occurs when the frequency of the …

The mixing of two sets of mutually coherent beams, termed double two-beam mixing, is
considered. At low modulation depth, combination gratings of the primaries are analyzed …
