摘　　要：为了解决由热效应引起的硅基微环器件工作状态不稳定的难题,提出了一种基于微环谐振器阵列低速正交微扰信号的大规模光子集成电路实时稳定控制技术,通过建立数值仿真模型验证了该方案能够通过单个检测通道实现对不同信道状态信息进行有效提取,并搭建了正交解调系统进行实验验证。仿真和实验结果证明,该方案能够实现大规模光子系统的稳定控制。In order to solve the problem of unstable working state of silicon-based microring devices caused by thermal effect, this paper proposes a real-time stability control technology for large-scale photonic integrated circuits based on microring resonator array low-speed orthogonal perturbation signals. It is verified that the scheme can effectively extract different channel state information through a single detection channel by buliding the numerical simulation model, and an orthogonal demodulation system is built for experimental verification. Simulation and experimental results show that the scheme can realize the stable control of large-scale photonic system.
