Abstract
A method for optical signal processing includes receiving an optical signal containing a plurality of frequency lines, defining at least two wavesets including an updatable random subset of the frequency lines, receiving a data stream, modulating the optical signal with the data stream, encrypting the data stream by extracting the subset of the frequency lines of the at least two wavesets from the modulated optical signal, and phase coding the subset of frequency lines of the at least two wavesets in the modulated optical signal.
