Near-Infrared 3D Imaging with Upconversion Detection
He Zhang, Santosh Kumar, Yong Meng Sua +2
We demonstrate a photon-sensitive, three-dimensional camera by active near-infrared illumination and fast time-of-flight gating. It uses pico-second pump pulses to selectively up-c…

A Programmable Spatiotemporal Quantum Parametric Mode Sorter
Malvika Garikapati, Santosh Kumar, He Zhang +2
We experimentally demonstrate a programmable parametric mode sorter of high-dimensional signals in a composite spatiotemporal Hilbert space through mode-selective quantum frequency…
