随着包括人工智能在内的信息通信技术的迅速发展，高效和准确的决策变得越来越重要。在这里，我们提出并实验演示了一种基于环形激光器的片上集成光子决策器。环形激光器表现出顺时针和逆时针振荡动力学之间的自发切换；我们利用这种性质来解决多臂强盗问题。自发切换动力学为寻找准确的决策提供了有效的探索。实验演示了在线决策，包括对不确定环境的自主适应。这项研究为直接利用环形激光器固有的波动物理或集成光子学技术实现或加速智能功能铺平了道路。
Efficient and accurate decision making is gaining increased importance with the rapid expansion of information communication technologies including artificial intelligence. Here, we propose and experimentally demonstrate an on-chip, integrated photonic decision maker based on a ring laser. The ring laser exhibits spontaneous switching between clockwise and counter-clockwise oscillatory dynamics; we utilize such nature to solve a multi-armed bandit problem. The spontaneous switching dynamics provides efficient exploration to find the accurate decision. On-line decision making is experimentally demonstrated including autonomous adaptation to an uncertain environment. This study paves the way for directly utilizing the fluctuating physics inherent in ring lasers, or integrated photonics technologies in general, for achieving or accelerating intelligent functionality.
