- Abstract: 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 detection and
Fourier-transform analysis. A sub-wavenumber spectral resolution allows for
rotational-line-resolving spectroscopy of gaseous samples in a spectral
bandwidth of over 700$\,$cm$^{-1}$. We use methane transmission spectra around
3.3$\,\mu$m wavelength to characterize the spectral resolution, noise
limitations and transmission accuracy of our device. The combination of
nonlinear interferometry and Fourier-transform analysis paves the way towards
performant and efficient mid-infrared spectroscopy with near-infrared
detection.

We investigate the bistability in a small Fabry-Perot interferometer (FPI) with the optical wavelength size cavity, the nonlinear Kerr medium and only a few photons, on average, excited by the external quantum field.
Multiple stationary states of the FPI cavity field with different spectra are possible at realistic conditions, for example, in the FPI with the photonic crystal cavity and the semiconductor-doped glass nonlinear medium.

Experimental demonstrations have been limited to wavelengths shorter than 5 um or in the terahertz region, and have not been realized in the so-called fingerprint region of 1500- 500 cm-1.
