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 …

Carver Mead introduced “neuromorphic engineering”[1] as an interdisciplinary approach to
the design of biologically inspired neural information processing systems, whereby …

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 …

A two-beam coupling interaction of an information-bearing beam with a copy of itself in a
photorefractive medium changes the spatiotemporal nature of the beam. We analyze the …

This chapter reviews advances in hardware learning and adaptation in synthetic neural
systems. Research in the field draws inspiration from neurobiology, physics of computation …

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 …

Photoconductive and dielectric dependence of gain and phase-shift in the coupled
unidirectional photorefractive ring resonators (UPRR) have been analyzed for the case of …

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