Abstract

Spontaneous parametric down-conversion can produce pairs of entangled photons with very different wavelengths. Using SPDC, the scheme of Imaging with Undetected Photons promises to be a versatile tool to facilitate imaging in various spectral ranges and various interferometer designs and geometries. Here, we tackle the task of Imaging with Undetected Photons with a Mach-Zehnder-type Interferometer in MIR. With imaging achieved in a preliminary setup, we investigate the limitations set by nonlinear conversion efficiencies, optical resolution, laser power, and fluorescence of optics on our way to Imaging with Undetected Photons in MIR.
