Terahertz CMOS spectroscopic system-on-chip -- Towards precise timing and rapid gas sensing

Harnessing the rotational spectra of gas molecules opens new opportunities for Terahertz CMOS integrated circuits. This talk introduces an ultra-stable, chip-scale molecular clock achieving an “atomic” clock level stability by locking to a molecular beat for future mobile timing, and also a fast speed dual-frequency-comb gas sensor that analyzes human breath without ambiguity.
