This paper investigates the possibilities of complex nonlinear dynamic signal generation

All-optical control of impulse parameters is realized via a dynamical transmission four-wave
mixing. We show that the nonlinear system, which includes both coupled wave equations …

We investigate spatio-temporal dynamics of two-wave mixing processes in a photorefractive

The phase part of the system of equations describing two-wave mixing in a photorefractive
strongly inertial medium is studied analytically and numerically. It is shown that the solution …

We show that the standard model of four-wave mixing in a photorefractive crystal predicts
the appearance of deterministic chaos. In this model there is a single (transmission) grating …

Abstract Four-wave mixing (4WM) in photorefractive media has been studied intensively
during recent years. While the steady-state properties of this process are rather well known …

The effect of transverse coupling in a photorefractive oscillator is studied. From the study the
condition for stable optical patterns of multimode oscillation is given analytically and verified …

We explore phase conjugation of transient optical signals through the mechanism of
degenerate four-wave mixing in photorefractive media. Our model is governed by Maxwell's …

The counterpropagation of two laser beams through wave mixing in nonlinear optics may
lead to spatiotemporal structures in the transverse beam profiles. We theoretically …

The formation of patterns in two transverse dimensions in photorefractive two-wave mixing
with a single feedback mirror is investigated theoretically. We perform numerical simulations …
