摘　　要：凭借小体积、低功耗、可重构、低成本等优势,片上集成相干光源成为光计算、自动驾驶、高速光互联、5G/6G通信等领域极具潜力的光源方案。微腔集成相干光源结合片上集成和腔增强效应,显著增加了腔内光场功率,降低了泵浦阈值。该文介绍克尔光频梳、微腔受激拉曼激光、二阶非线性光梳和微腔增强电光梳四大类微腔集成相干光源的原理和研究进展,针对谱宽、噪声、效率、功率四大关键性能指标逐一进行分析,介绍基于微腔集成相干光源在通信应用中的研究进展,并对其未来发展趋势进行展望。With advantages such as small footprint,low power consumption,reconfigurability and low cost,chip-integrated coherent light sources have become a highly promising scheme,applied in optical computing,autonomous driving,high-speed optical interconnection,5G/6G communications,etc.Combining on-chip integration and cavity enhancement effects,microcavity-based integrated coherent light sources significantly improve the intracavity light power as well as reducing the pump threshold.This paper introduces in detail the principle and research progress of four kinds of microcavity integrated coherent light sources:Kerr frequency combs,microcavity stimulated Raman lasers,quadratic combs and microcavity-enhanced electro-optical combs.The four key parameters of spectrum width,noise,efficiency and power are analyzed one by one,and the research progresses of microcavity-based integrated coherent light sources in communication applications are introduced.At last their future development trends are prospected.
