Abstract

The application of electro-optic frequency combs to direct absorption spectroscopyfootnote{D.A. Long et al., textit{Opt. Lett.} textbf{39,} 2688 (2014)} has increased research interest in high-agility, modulator-based comb generation. This talk will review common architectures for electro-optic frequency comb generators as well as describe common self-heterodyne and multi-heterodyne (i.e., dual-comb) detection approaches. In order to achieve a sufficient signal-to-noise ratio on the recorded interferogram while allowing for manageable data volumes, broadband electro-optic frequency combs require deep coherent averaging,footnote{A.J. Fleisher et al., textit{Opt. Express} textbf{24,} 10424 (2016)} preferably in real-time. Applications such as cavity-enhanced spectroscopy, precision atomic and molecular spectroscopy, as well as time-resolved spectroscopy will be introduced.
