Single-shot Subnoise Signal Recovery by Coherent Spectral Energy Redistribution
Benjamin Crockett, Luis Romero Cortés, Saikrishna Reddy Konatham, José Azaña · Conference on Lasers and Electro-Optics · 2019
We demonstrate single-shot recovery of subnoise signals, completely buried under random in-band noise, through combinations of phase manipulations derived from Talbot effect theory, allowing for reconstruction of signals with a time-bandwidth-product of up to 24.
