Four associative memory schemes (Hopfield associative memory, generalized inverse
associative memory, spectral associative memory and Ho-Kashyap associative memory) …

Four-wave mixing with cross-polarised pump beams is known to produce infinite phase
conjugate reflectivities at a coupling strength of ΓL= 4 in the undepleted pumps …

The objective of this dissertation is to study the dynamics of the photorefractive effect in order
to analyze the process of multiplexed holographic recording in photorefractive crystals. A …

Single crystals of the electro-optic compound 2-cyclo-octylamino-5-nitropyridine (COANP)
doped with small amounts of 7, 7, 8, 8-tetracyanoquinodimethane (TCNQ) have been shown …

We describe the use of optical memory disks in optical pattern recognition systems.
Algorithmic and architectural issues associated with the realization of such systems are …

The prediction of a critical slowing down effect in four wave mixing has been made which
leads to the concept of a constant gain-bandwidth product for four wave mixing. The effects …

In the previous chapter nonlinear optical waveguides were discussed and in many aspects
the aim of this work is to try to emulate digital electronic circuits—switching, serial …

When three incident mutually coherent beams interact by degenerate four wave mixing in a
photorefractive medium, four gratings are induced: 1 (1) a transmission grating,(2) a …
