The message-decryption process of subtracting chaotic synchronization carrier from receiving signal is explained by modeling and numerically solving the rate equations for semiconductor lasers. An experimental system of wavelength division multiplexing passive optical network (WDM-PON) based on chaotic-light secure communications is first built up. The bidirectional transmissions of downstream and upstream data are experimentally realized with only two lasers and a single wavelength channel in a WDM fiber-optic link. When the data rate is 1.25 Gb/s, the secure transmission distance can be up to 11 km with SSMF of G.652. After sampling and decision, the BER of the recovered messages is calculated to be approximately 1×10−4.
