摘　　要：分析了孤子微梳泵浦能量转换效率低的原因,介绍了目前已提出的几种提高孤子微梳泵浦光能量转换效率的技术方案,包括激发孤子晶体光梳利用多孤子结构、正常-反常色散双腔耦合泵浦光循环存储结构、微腔-光纤/波导环泵浦光反馈耦合干涉结构、主-副微环腔耦合超模谐振峰劈裂结构等,并分析了这些方案的优缺点。在此基础上,给出了本课题组对反馈耦合腔的优化设计,仿真模拟结果显示,单孤子微梳的泵浦光转换效率可超过25%。最后,对孤子微梳的低能耗产生方案作出总结和展望,为微腔孤子光频梳泵浦能量转换效率提高技术的发展与应用提供理论参考。In this paper,the reasons for low energy conversion efficiency of soliton microcomb pump are analyzed,and several proposed technical schemes to improve the pump light energy conversion efficiency of soliton microcombs are introduced,including pump energy circulation storage structure of normal-anomalous dispersion double-cavity coupled structure,super-mode resonance splitting structure of master-auxiliary microring coupled-cavity structure,pump feedback waveguide coupled microcavity interference structure,etc.The advantages and disadvantages of each scheme are analyzed.On this basis,the optimal design of the pump feedback waveguide coupling cavity is given,and the simulation result shows that the pump light conversion efficiency of the single soliton micro comb can exceed 25%.At the end of this paper,the low energy consumption generation schemes of soliton microcombs are summarized and prospected,providing theoretical references for the development and application of techniques to improve the pump energy conve rsion efficiency of microcavity soliton optical frequency combs.
