摘要
芯片级原子钟是一种小型、低功耗、高精度的时间频率设备,与微惯性测量组合和卫星导航技术相结合,形成微型导航定位授时单元,可广泛应用于国民经济、军事领域和国家安全等方面。本文介绍了国内外芯片级原子钟的研究进展及现状,阐述了芯片级原子钟研制的难点及需要突破的关键技术,包括微型原子气室制备技术、微机电系统集成技术和芯片级光学频率梳技术等,最后对芯片级原子钟的发展趋势进行了展望。
The chip scale atomic clock is a small,low-power,high-precision time and frequency device.Combining the chip scale atomic clock and the micro inertial measurement unit with the receiver of the global navigation satellite system,a micro positioning navigation and timing unit is formed,which can be widely used in the fields of national economy,military fields and national security.In this paper,the research progress of the chip scale atomic clock at home and aboard is introduced firstly.The difficulties and key technologies in the development of chip scale atomic clock are also expatiated,including micro atomic vapor cell preparation technology,micro electro mechanical system integration technology and chip scale optical frequency comb technology.Finally,the development trend of chip scale atomic clock is prospected.
