用于机器学习加速的大规模集成光电混沌

导读

南京航空航天大学何吉骏教授、朱丹教授、潘时龙教授等团队针对传统非线性电路速度受限、现有光学混沌方案难以兼顾单通道吞吐率与多通道可扩展性的问题，团队提出并设计了一种集成微腔光梳-光电混沌引擎（iMOCE）。该团队通过用混沌态的微腔光梳驱动一个光电非线性腔体，实现了大规模并行的混沌信号产生，每个通道的6-dB带宽达到25 GHz，较先前的微腔光梳方法提升了两个数量级；该系统同时实现了32.768 Tbps的总随机比特生成速率，并在四种典型机器学习任务中，将每次推理时间相比MCU/GPU缩短了约两个数量级，从而验证了iMOCE作为一种可扩展且具备大规模并行能力的混沌基元，能够有效加速机器学习计算。

研究成果于2026年6月12日以题为“Large-scale integrated optoelectronic chaos for machine learning acceleration”发表在《Nature Communications》上。
