Stationary and nonstationary symmetry-breaking optical patterns in a resonant bilayer.
I.V. Babushkin, Yu.A. Logvin, and N.A. Loiko

Optical pattern formation is studied in a system consisting of two identical thin layers of resonance medium illuminated by light fields of equal intensity from both sides. It is shown that transverse optical patterns emerged in the system may be either symmetrical (identical for both layers) or symmetry-breaking. The influence of the inter-layer mistuning (distance between the layers) on the type of instability is elucidated. When delay effects are taken into account, a relationship between the symmetry-breaking, bistability and the Hopf-Ikeda transverse instabilities is revealed.
