Terahertz Frequency Comb High-Resolution Heterodyne Spectrometer

Francis Hindle, Alexandra Khabbaz, Anthony Roucou, Jean-Francois Lampin, Gaël Mouret

We demonstrate the advantages of THz frequency combs for high-resolution spectroscopy. This benefits from wide spectral coverage and the exact knowledge of the frequency position of each comb component. Heterodyne detection combined with a fast Fourier spectrometer enables rapid and simultaneous…
