摘要

微梳技术正在推动光频梳技术向芯片集成形式发展。在此，我们介绍了一种基于两点光分频（2P-OFD）技术的微波信号源。该系统使用频率微蜂窝将两个低噪声光振荡器的相对频率稳定性传递给微蜂窝重复率音调。这两个光振荡器基于半导体激光器，共同稳定在一个超稳定的法布里-佩罗腔上。通过对其重复率和梳状线频谱进行多次稳定性比较，确认了梳状频谱的一致性。研究结果强调了微梳作为光学和微波频率之间的相干链路所具有的卓越性能，以及微梳如何实现光学频率划分的简化、小型化架构。

Coherent Optical-to-Microwave Link Using an Integrated Microcomb

Microcombs are advancing optical frequency comb technology towards a chip-integrable form. Here, we characterize a microwave signal source based upon the two-point optical frequency division (2P-OFD) technique. The system uses a frequency microcomb to transfer relative frequency stability of two low-noise optical oscillators to the microcomb repetition rate tone. The two optical oscillators are based on semiconductor lasers jointly stabilized to an ultra-stable Fabry–Pérot cavity. The coherence of the comb spectrum is confirmed through multiple stability comparisons between its repetition rate and comb line spectrum. The results underscore the excellent performance of microcombs as coherent links between optical and microwave frequencies, and how they enable simplified, miniaturized architectures for optical frequency division.

期刊介绍： Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
