Upconversion Dual-comb Passive Spectroscopy of Mid-IR Incoherent Light
Mingchen Liu, Matthew Heyrich, Sichong Ma +1
We introduce cross-comb correlation spectroscopy, which correlates signals from asynchronous sum-frequency sampling of mid-IR incoherent light with two near-IR combs. We experiment…

Quadratic-soliton-enhanced mid-IR molecular sensing
Robert M. Gray, Mingchen Liu, Selina Zhou +3
Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead…
