6. Conclusions
In this paper, the mismatch of the wavelength between
the message and the chaotic carrier in the chaotic optical
communication with chaos-masking has been experi-
mentally investigated. The results show that the decryp-
tion performance of the receiver can be improved when
the wa velength of the message is greater than that of the
chaotic carrier. When the wavelength offset is set to 0.12
nm, high-speed secure communication with a message of
2.5 Gbits/s can be achieved. The results presented here
may provide some useful suggestions for the practical
applications of secure chaotic op tic a l c ommunications.
