Abstract :
Successful high-speed fiber-optic transmission using a four-chaotic-semiconductor-laser system is numerically demonstrated. The system performance is benefited from the properties of bandwidth enhancement and the implementation of a two-channel scheme. The bit-error rate of the recovered message is evaluated for different fiber lengths and message bit rates, respectively. In particular, acceptable communication performance can be achieved for a bit rate up to 8 Gb/s when the fiber length is approximately 60 km. Such a system could lead to high-speed chaos-based encryption/decryption even if the fiber transmission module is considered.
