In this article, it is shown that multimode periodic segmented waveguides (PSW) are versatile optical systems in which properties of wave chaos can be highlighted. Numerical wave analysis reveals that structures of quantum phase space of PSW are similar to Poincaré sections which display a mixed phase space where stability islands are surrounded by a chaotic sea. Then, unexpected light behavior can occur such as, input gaussian beams do not diverge during the propagation in a highly multimode waveguide.
本文表明，多模周期分段波导（PSW）是一种多功能光学系统，可以突出展示波混沌的特性。数值波分析表明，PSW 的量子相空间结构类似于 Poincaré 截面，它们显示出一种混合相空间，其中稳定岛被混沌海包围。然后，可能会出现意想不到的光行为，例如，在高度多模波导中传播时，输入高斯光束不会发散。
