Quantum undetected optical projection tomography

Dataset of quantum optical projection tomography. Each sub-folder contains a series of images representing a phase scan taken at one orientation angle of the subject (angle is given in the subfolder name - in degrees).

Phase-matching-free sensing with undetected light using a nonlinear thin-film metasurface

Abstract In this article, we report classical sensing with undetected light at a wavelength of 1500 nm, detected on a silicon camera at 580 nm, using four-wave mixing from a plasmonic metasurface. The bidirectional nonlinear scattering due to inherent reflections from such thin n...
