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…
Time-Spatial Mode Selective Quantum Frequency Converter
Santosh Kumar, He Zhang, Prajnesh Kumar +3
We experimentally demonstrate a mode-selective quantum frequency converter over a compound spatio-temporal Hilbert space. We show that our method can achieve high-extinction for hi…
Robust and Efficient Single-Pixel Image Classificationwith Nonlinear Optics
Santosh Kumar, Ting Bu, He Zhang +2
We present a hybrid image classifier by mode-selective image upconversion, single pixel photodetection, and deep learning, aiming at fast processing a large number of pixels. It ut…
Single-Pixel Pattern Recognition with Coherent Nonlinear Optics
Ting Bu, Santosh Kumar, He Zhang +2
We propose and experimentally demonstrate a nonlinear-optics approach to pattern recognition with single-pixel imaging and deep neural network. It employs mode selective image up-c…
A Super-resolution Optical Classifier with High Photon Efficiency
He Zhang, Santosh Kumar, Yu-Ping Huang
We propose and demonstrate a photon-efficient optical classifier to overcome the Rayleigh limit in spatial resolution. It utilizes mode-selective sum frequency generation and singl…
Large-scale Ising Emulation with Four-Body Interaction and All-to-All Connection
Santosh Kumar, He Zhang, Yu-Ping Huang
We propose and demonstrate a nonlinear optics approach to emulate Ising machines containing up to a million spins and with tailored two and four-body interactions with all-to-all c…
Mode Selective Image Upconversion over Turbulence
He Zhang, Santosh Kumar, Yu-Ping Huang
We experimentally study a nonlinear optical approach to selective manipulation and detection of structured images mixed with turbulent noise. Unlike any existing adaptive-optics me…
Mode-selective Image Upconversion
Santosh Kumar, He Zhang, Stephanie Maruca +1
We study selective upconversion of optical signals according to their detailed transverse electromagnetic modes, and demonstrate its proof of operations in a nonlinear crystal. The…
