摘要
Signal-masked optical communication utilizing amplified spontaneous emission (ASE) from an optical amplifier is proposed and demonstrated. Data to be transmitted is embedded in spontaneous-spontaneous beat noise of the ASE light and is demodulated by differentially detecting the signal and reference channels. The feasibility of the scheme is demonstrated by experiments, where 622-Mbit/s data was successfully recovered at the receiver while the transmitted data was concealed in the signal channel alone.
