Pattern formation in nonlinear optical systems with feedback — •Guido Krüger and Rudolf Friedrich — Institute for Theoretical Physics University of Münster, Wilhelm.-Klemm-Str. 9, 48159 Münster

Optical systems are of growing interest in communication technology. Especially the combination of optical signals is a important task to produce optical switches.

In our study, we investigate two nonlinear Sodium vapor cells with feedback theoretically as well as numerically. The emerging patterns, which arise due to the nonlinearity and the feedback, will be presented and discussed (Hexagons, squares, stripes, honeycombs, labyrinthine, quasipatterns and solitary structures). Furthermore our interest is to perform a logical operation with these two cells to check if it is possible to make a optical switch.
