Spectroscopy in the molecular fingerprint spectral region (6.5-20 $\mu$m) yields critical information on material structure for physical, chemical and

Versatile silicon-waveguide supercontinuum for coherent mid-infrared spectroscopy

Author(s)
Nima Nader, Daniel Maser, Flavio Caldas da Cruz, Abijith S. Kowligy, Henry R. Timmers, Jeffrey T. Chiles, Connor D. Fredrick, Daron A. Westly, Richard P. Mirin, Jeffrey M. Shainline, Scott A. Diddams
Infrared spectroscopy is a powerful tool for basic and applied science. The rich “spectral fingerprints” of compounds in the 3 um - 20 um region provide a means

Coherent Frequency Combs for Spectroscopy in the 3-5 Micron Region
