Pattern Formation in Unidirectional Coupled Nonlinear Optical Systems — Guido Krüger and •Rudolf Friedrich — Institute for Theoretical Physics, University of Münster, Wilhelm-Klemm-Str. 9, 48149 Münster

We present theoretical and numerical studies of two unidirectional coupled optical single feedback mirror systems. A single optical single feedback mirror system (OSFMS) can exhibit various structures such as 8-fold quasipatterns, hexagons, squares or solitary structures. In our work we consider two unidirectional coupled OSFMS and study the emerging patterns in the second cell. Our main focus in this talk will be on the interaction of solitary objects and the interplay of solitary objects with 8-fold quasipatterns. The coupling of these patterns allows the creation of various new patterns, that do not exist in a single OSFMS.
