Precise Photon Arrival Time Measurement via Time to Frequency Demultiplexing
Usman Khan, Santosh Kumar, Daniel Lopez +3
We demonstrate a nonlinear-optics approach to precise measurement of photon arrival time, by translating the temporal information of single photons to a wavelength distribution of…

A Robust Super-Resolution Classifier by Nonlinear Optics
Ishan Darji, Santosh Kumar, Yu-Ping Huang
Spatial-mode projective measurements could achieve super-resolution in remote sensing and imaging, yet their performance is usually sensitive to the parameters of the target scenes…
