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…
Observation of Distinct Phase Transitions in a Nonlinear Optical Ising Machine
Santosh Kumar, Zhaotong Li, Ting Bu +2
Optical Ising machines promise to solve complex optimization problems with an optical hardware acceleration advantage. Here we study the ground state properties of a nonlinear opti…
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…
Efficient Frequency Doubling with Active Stabilization on Chip
Jia-Yang Chen, Chao Tang, Mingwei Jin +6
Thin-film lithium niobate (TFLN) is superior for integrated nanophotonics due to its outstanding properties in nearly all aspects: strong second-order nonlinearity, fast and effici…
Efficient Reservoir Computing using Field Programmable Gate Array and Electro-optic Modulation
Prajnesh Kumar, Mingwei Jin, Ting Bu +2
We experimentally demonstrate a hybrid reservoir computing system consisting of an electro-optic modulator and field programmable gate array (FPGA). It implements delay lines and f…
