Abstract
Given prior knowledge of the spectral statistics, the SNR of optical waveforms can be manipulated in a reversible manner. We introduce this concept and discuss its potential application to encryption and context-aware detection of weak signals in noisy environments. The same technology performs single shot sparse sampling for optical data compression.
