In recent years, there has been a rapid expansion in the field of nonlinear optics as weIl as
in the field of neural computing. Up to date, no one would doubt that nonlinear optics is one …

An operator approach to two-beam coupling in photorefractive media for which each beam
is composed of information that varies in both space and time reduces the problem to a …

We analyze the stability of two recently demonstrated photorefractive resonator circuits. The
analysis is based on single-mode models of the multimode circuits. The flip-flop, which …

We present a photorefractively pumped ring resonator for the formation of self-organized.
topology-preserving mappings. The self-imaging ring resonator with saturable gain and loss …

The optical feature extractor is a photorefractive ring oscillator that can identify the strongest
spatio-temporal component of its input space. The theoretical sections discuss the design …

The self-organized representation of images by photorefractive oscillator modes is studied
experimentally and theoretically. Two types of representations are demonstrated: a feature …

We analyze reflexive photorefractive coupling of an information-bearing beam carrying
several distinct spatiotemporal features, with emphasis on the coupling-induced change in …

La propagation de signaux optiques à travers des milieux diffusants ou multimodes est un
problème largement étudié dans la communauté scientifique. De nombreuses études ont …

Modules that perform photorefractive two-beam coupling operations have been built,
characterized, and tested. These portable modules, interconnected by fiber optics, dispense …
