Keller Compact laser frequency combs covering the midinfrared “fingerprint” spectral region are desirable light sources for high-sensitivity, high-resolution detection of target molecules. The authors leverage the nonlinear properties of chip-scale Si 3 N 4 and periodically poled LiNbO 3 waveguides to obtain a tunable, energy-efficient mid-IR frequency comb. Here the pulse energy needed for a given power per comb line is nearly two orders of magnitude lower than for conventional systems. These results are promising for applications in environmental, medical, and industrial diagnostics. [Phys. Rev. Applied 6, 054009] Published Fri Nov 18, 2016
