我们研究了一个对称势阱双阱波导中自发对称破缺的例子。超过临界功率后，系统的基态变得不对称。数值说明的效果，并通过Galerkin截断，清楚地显示了从对称到不对称的稳态分岔定量分析。当探测光束被适当地发射到光折变材料中的光诱导光子晶格中时，这种现象也被实验证明。(c)2005 Elsevier B.V.保留所有权利。
We examine an example of spontaneous symmetry breaking in a double-well waveguide with a symmetric potential. The ground state of the system beyond a critical power becomes asymmetric. The effect is illustrated numerically, and quantitatively analyzed via a Galerkin truncation that clearly shows the bifurcation from a symmetric to an asymmetric steady state. This phenomenon is also demonstrated experimentally when a probe beam is launched appropriately into an optically induced photonic lattice in a photorefractive material. (c) 2005 Elsevier B.V.
