Ma. Vorontsov et al., DIFFRACTIVE PATTERNS IN A NONLINEAR-OPTICAL 2-DIMENSIONAL FEEDBACK-SYSTEM WITH FIELD ROTATION, Chaos, solitons and fractals, 4(8-9), 1994, pp. 1701-1716
Nonlinear optical systems using either a Kerr slice or liquid crystal
light valve and having field rotation in the 2D optical feedback loop
are analyzed. A Neumann series approach is used to study pattern forma
tion. We show that when there is strong diffraction in the optical fee
dback loop polygon patterns ('Akhseals') appear. Interactions between
Akhseals occur in the form of Winner Takes All (WTA) dynamics. Results
of the numerical simulations are presented.
