Mid-IR spectroscopy with NIR grating spectrometers
Paul Kaufmann, Helen M. Chrzanowski, Aron Vanselow +1
Mid-infrared (mid-IR) spectroscopy is a crucial workhorse for a plethora of analytical applications and is suitable for diverse materials, including gases, polymers or biological t…
Reconstruction of photon number conditioned states using phase randomized homodyne measurements
H. M. Chrzanowski, S. M. Assad, Julien Bernu +5
We experimentally demonstrate the reconstruction of a photon number conditioned state without using a photon number discriminating detector. By using only phase randomized homodyne…
Mid-Infrared Microscopy via Position Correlations of Undetected Photons
Inna Kviatkovsky, Helen M. Chrzanowski, Sven Ramelow
Quantum imaging with undetected photons (QIUP) has recently emerged as a new powerful imaging tool. Exploiting the spatial entanglement of photon pairs, it allows decoupling of the…
Low random duty-cycle errors in periodically-poled KTP revealed by sum-frequency generation
Felix Mann, Helen M. Chrzanowski, Sven Ramelow
Low-noise quantum frequency conversion in periodically-poled nonlinear crystals has proved challenging when the pump wavelength is shorter than the target wavelength. This is - at…
