通过微波倍频产生的太赫兹振荡器在实现低相位噪声方面面临着困难。基于光子学的技术,即通过光电转换将光学两个音调转换为太赫兹波,如果这两个音调之间的相对相位噪声得到很好的抑制,那么它是很有前途的。在这里,具有低相位噪声的太赫兹(≈560 GHz)波是由稳频、耗散克尔微谐振器孤子梳提供的。在双波长延迟自外差干涉仪中,梳子的重复频率被稳定在一根长光纤上,显著降低了太赫兹波的相位噪声。还展示了一种测量技术来表征超出倍频微波极限的太赫兹波的相位噪声,表明太赫兹波的相位噪声优于任何其他光子太赫兹振荡器(>300 GHz)。
THz oscillators generated via frequency-multiplication of microwaves are facing difficulty in achieving low phase noise. Photonics-based techniques, in which optical two tones are translated to a THz wave through opto-electronic conversion, are promising if the relative phase noise between the two tones is well suppressed. Here, a THz (≈560 GHz) wave with a low phase noise is provided by a frequency-stabilized, dissipative Kerr microresonator soliton comb. The repetition frequency of the comb is stabilized to a long fiber in a two-wavelength delayed self-heterodyne interferometer, significantly reducing the phase noise of the THz wave. A measurement technique to characterize the phase noise of the THz wave beyond the limit of a frequency-multiplied microwave is also demonstrated, showing the superior phase noise of the THz wave to any other photonic THz oscillators (>300 GHz).
