We experimentally report on the detection of chaos from a free-running commercial broad-area vertical-cavity surface-emitting laser (VCSEL) without the need for external perturbation such as optical feedback, injection, or current modulation. The evolution of nonlinear dynamics leading to chaotic behavior is studied, and the system's complexity is characterized using chaos titration and correlation dimension. We link the occurrence of chaos with the complex interplay between the spatial laser mode competition and polarization dynamics.
我们通过实验报告了从一个自由运行的商用宽面垂直腔面发射激光器（VCSEL）中检测到混沌，而无需诸如光反馈、注入或电流调制等外部扰动。研究了导致混沌行为的非线性动力学的演变，并使用混沌滴定和关联维数来表征系统的复杂性。我们将混沌的出现与空间激光模式竞争和偏振动力学之间的复杂相互作用联系起来。
