Abstract
Nonlinear interferometers using correlated photon pairs allow mid-infrared spectroscopy with near-infrared detection. In our work, we combine nonlinear interferom- etry with a measurement scheme and analysis in analogy to classical Fourier-transform spectroscopy, which enhances the spectroscopic performance.
