Abstract

Security improvement of the stealth channel by using a novel time-domain direct current (DC) phase shift en/decoding OCDMA scheme is demonstrated. The time-domain DC phase shift encoded OCDMA signal, which introducing a phase shifts without a corresponding notch in the temporal waveform, has been stealth transmitted over a public wavelength division-multiplexing (WDM) network. Compared with equivalent phase shift (EPS) en/decoder, the sensitivity of the stealth channel based on DC phase shift en/decoder is promoted 4dB.
