摘要：Chip-scale molecular clock (CSMC), as a portable, “atomic”-grade time standard, locks to the sub-THz rotational spectra of the polar gaseous molecules (e.g., carbonyl sulfide, OCS). It features a low cost, a short start-up time, and environmental robustness. The quality factor (Q) of the unsaturated rotational spectra of OCS ( Q=105∼106 ) is lower than that of the coherent population trapping (CPT) in alkaline atoms ( Q=106∼107 ) used in chip-scale atomic clocks (CSACs). Thanks to its higher spectra detection signal-to-noise ratio (SNR), the CSMCs demonstrate highly competitive short-to-medium
