Quantum Fourier-Transform Infrared Spectroscopy in the Far-Infrared Region
2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)(2022)
Abstract
Quantum Fourier-transform (QFTIR) spectroscopy enables the estimation of infrared optical properties only by detecting visible or near-infrared light, harnessing the quantum interference between the successive photon-pair generation processes. We demonstrate QFTIR spectroscopy in the finger print region around 10μm.
