Silicon-chip-based mid-infrared dual-comb spectroscopy

HIGHLIGHTS

• who: Mengjie Yu from the Columbia University, New York, NY, USA have published the research work: Silicon-chip-based mid-infrared dual-comb spectroscopy, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 12/01/2017
• what: The authors compare the results to the absorption spectrum the authors measured using a Fourier transform spectrometer (Bruker Vertex 70) equipped with a globar, a CaF2 beam-splitter and a InSb detector.
• future: By individually controlling the reverse-bias-voltage applied on the PIN junctions the line spacings of the microresonators can be finely controlled independently such . . .
