摘要

We have investigated the synchronization of chaotic duabring erbium-doped fibre lasers using the delay feedback injection scheme. Numerical simulation shows that two chaotic dual-ring erbium-doped fibre lasers can be well synchro nized if the strengths of delay feedback and injection are suitable. Even though the effects of the noises and the difference between the two lasers are considered, the twins can still reach good synchronization. Secure communication could be realized using the scheme of message-masking based on the synchronization of the chaotic dual-ring erbium-doped fibre lasers.
