摘要

光子振荡器能够通过光学手段产生光谱纯净的无线电、微波和毫米波信号。这种振荡器利用长寿命光储能元件（如光延迟线或空腔）来产生信号。我们在这里展示的是，利用在氟化镁耳语廊模式谐振器中产生的克尔梳，其品质因数超过十亿，可以在 10 kHz 频率偏移时产生相位噪声接近 -120 dBc/Hz 的 W 波段微波频率信号。这一发现为实现更高载波频率的微型微波光子频率发生器和合成器铺平了道路。

Low Noise W-Band Photonic Oscillator

Photonic oscillators are capable of generating spectrally pure radio, microwave and millimeter wave signals by optical means. The oscillators take advantage of a long lifetime optical energy storage element, such as optical delay line or a cavity, to produce the signals. We here show that using a Kerr comb generated in a magnesium fluoride whispering gallery mode resonator with quality factor exceeding a billion one can generate W-band microwave frequency signals with phase noise approaching −120 dBc/Hz at 10 kHz frequency offset. The observation paves the way towards realization of the miniature microwave photonic frequency generators and synthesizers at higher carrier frequencies.

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.
