Abstract

The system tolerance to the dispersion of optical steganography and the deployment of dispersion to enhance secure transmission has been experimentally demonstrated and theoretically studied. Since the stealth signal is carried by amplified spontaneous emission noise, which has a much wider bandwidth compared with the laser carrier, the stealth channel is more sensitive to dispersion and has less tolerance to the uncompensated dispersion. On the other hand, the dispersion effect in the stealth channel can be employed to hide the stealth signal in the time domain. The extra dispersion at the transmitter and the receiver functions as a key pair for the optical encryption and the optical steganography.
