Scanless quantum Fourier-transform mid-infrared spectroscopy for rapid high-sensitivity hyperspectral mapping
Paul Gattinger, Bettina Heise, Andreas W. Schell +3
Fourier-transform infrared (FTIR) spectroscopy is a well-established technique for qualitative and quantitative chemical analysis. Classical FTIR systems rely, however, on direct m…
Quantum metrology with undetected mid-infrared photons for applied non-destructive testing
Paul Gattinger, Andreas W. Schell, Maja Buchegger +2
Metrology with undetected photons is an emerging technique that leverages quantum effects and photon correlations (entanglement) to retrieve valuable information in a target spectr…
Infrared photonics for healthcare: A roadmap for proactive and predictive health management
Borislav Hinkov, Johannes Kunsch, Werner Mäntele +82
The field of infrared (IR) photonics is currently undergoing remarkable progress, moving rapidly towards practical sensing applications demanded by medical therapy and diagnostics…
Dispersion in nonlinear interferometry: implications for optical coherence tomography with undetected photons
Ivan Zorin, Paul Gattinger
Nonlinear SU(1,1) quantum interferometers based on non-degenerate optical parametric down-conversion exhibit strong unbalanced group velocity dispersion (GVD). This feature is intr…
Quantum Fourier Transform Infrared Spectroscopy: Evaluation, Benchmarking and Prospects
Paul Gattinger, Andreas W. Schell, Sven Ramelow +2
Sensing with undetected photons has enabled new, unconventional approaches to Fourier transform infrared (FTIR) spectroscopy. Leveraging properties of non-degenerated entangled pho…
Time-encoded mid-infrared Fourier-domain optical coherence tomography
Ivan Zorin, Paul Gattinger, Andrii Prylepa +1
We report on a technically simple approach to achieve high-resolution and high-sensitivity Fourier-domain OCT imaging in the mid-infrared range. The proposed OCT system employs an…
