Research progress on technology for improving pump energy conversion efficiency of microcavity soliton optical frequency combs
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 ana-lyzed.On this basis,the optimal design of the pump feedback waveguide coupling cavity is given,and the simulation re-sult 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 conversion effi-ciency of microcavity soliton optical frequency combs.
