我们报告了平面谐振器光场中存在的各种周期性横向图案和稳定的局域结构，其表现出半导体在带边附近的散焦可饱和非线性。我们预测所有可行模式以及局部状态的多稳定性。无论相同还是不同，稳定的局域态都可以组织成簇或新型周期性模式（超晶格）。局域态通过振荡尾部的相互作用允许形成具有相同基本单元但具有不同晶格间距的图案。
We report on the existence of various periodic transverse patterns and stable localized structures in the optical field of a planar resonator, which exhibits the defocusing saturable nonlinearity of a semiconductor near the band edge. We predict multistability of all feasible patterns as well as of the localized states. Being equal as well as different, stable localized states can organize as clusters or new kinds of periodic patterns (superlattices). The interaction of localized states via their oscillating tails allows the formation of patterns with the same basic units but with different lattice spacing.
