摘要

我们展示了基于梳状锁定频率合成器的新型频域太赫兹光谱仪的功能，该光谱仪可提供绝对频率校准。扫描的固有稳定性和可重复性使快速数据采集与平均限时信噪比相结合。我们在超高质量whispering-gallery-mode谐振器的太赫兹精密光谱中演示了千赫兹级频率分辨率。我们分析了单谐振的耦合行为和温度调谐，并首次观察到不同模式系列的微小红移和蓝移。实验结果得到了有限元模拟的支持。

Ultra-high precision comb-locked terahertz frequency-domain spectroscopy of whispering-gallery modes

We demonstrate the capabilities of a novel frequency-domain terahertz spectrometer based on a comb-locked frequency synthesizer, which provides absolute frequency calibration. The inherent stability and repeatability of the scans allow for the combination of fast data acquisition with an average time-limited signal-to-noise ratio. We demonstrate kilohertz level frequency resolution in terahertz precision spectroscopy of ultra-high quality whispering-gallery-mode resonators. Spectra covering multiple free spectral ranges (>36 GHz) with sub-20 kHz resolution are acquired in 5 s. We analyze the coupling behavior and temperature tuning of single resonances and, for the first time, observe minute red and blue shifts of different mode families. The experimental results are supported with finite element simulations.
