Abstract
In this paper, the wavelength division multiplexing (WDM) between chaotic optical secure channel and conventional fiber-optic channel, and the WDM between two chaotic optical secure channels are experimentally investigated without the dispersion compensation during transmission. When the channel spacing is 3 nm, the two types of WDM in which each channel carries a 1.25-Gbits/s message, can be realized by optimizing the injection strength, transmission distance, optical launched power and the amplitude of the message. For the WDM between chaotic optical secure channel and conventional fiber-optic channel, the multiplexing distance can be up to 100 km, and for the WDM between two chaotic optical secure channels, the multiplexing distance can be up to 25 km.
