Silicon nanowire optical waveguides dramatically broaden mid-infrared frequency comb spectra, scientists report. Frequency combs are commercially available in the visible and near-infrared spectral ranges. The mid-infrared spectral region (2-20?m), however, is still emerging. Many applications in spectroscopy, material science, security and industry process control, or chemical, biological and medical sensing would straightforwardly take advantage of mid-infrared photonics devices of higher performance.
