Nonlinear interferometer for Fourier-transform mid-infrared gas spectroscopy using near-infrared detection [PDF]
Opt. Express 29, 4035-4047 (2021), 2020 Nonlinear interferometers allow for mid-infrared spectroscopy with near-infrared detection using correlated photons. Previous implementations have demonstrated a spectral resolution limited by spectrally selective detection. In our work, we demonstrate mid-infrared transmission spectroscopy in a nonlinear interferometer using single-pixel near-infrared
