摘　　要：光学频率梳在精确测量和时频标准领域有着重要作用.随着技术进步,传统的光学频率梳向着小型化、集成化方向发展出微型光学频率梳、微型光机械耦合频率梳等新型技术.借鉴光子和声子之间的共性,纯粹基于机械振动的微机械频率梳为传感器技术、量子信息通信和极端环境下的应用提供了新的可能性.本文首先介绍了微机械频率梳的形成机理和数值仿真模型.在此基础上,本文主要阐述了微机械频率梳基于参数激励、内共振、碰撞效应、负耗散、负非线性摩擦等多种激发原理,总结了国内外现有的研究现状.此外,本文还从实际应用的角度让读者进一步了解微机械频率梳在相关领域的广泛应用,有助于了解微机械频率梳的自身特点和优势.最后,本文对未来发展方向进行了总结和展望.Optical frequency combs are pivotal in the realm of precise measurement and time-frequency standards.As technology advances,traditional optical frequency combs are trending towards miniaturization and integration,leading to the emergence of innovations such as micro-optical frequency combs and micro-optomechanical coupling frequency combs.Leveraging the similarities between photons and phonons,micromechanical frequency combs based solely on mechanical vibrations present novel opportunities for sensor technology,quantum information communication,and applications in extreme environments.This paper first introduces a numerical simulation model of micromechanical frequency combs.Based on it,it then elucidates the generation mechanisms of these combs,which include parametric excitation,internal resonance,contact and impact effects,negative dissipation,and negative nonlinear friction.Furthermore,from a perspective of practical application,this paper aims to enhance the reader's understanding of the extensive applications of micromechanical frequency combs in related fields,their distinctive characteristics and advantages,and provides a summary and outlook on future development directions.
