Long-haul dense wavelength division multiplexing between a chaotic optical secure channel and a conventional fiber-optic channel

Abstract: The purpose of this paper is to numerically investigate dense wavelength division multiplexing (DWDM) transmission between a chaotic optical secure channel and a conventional fiber-optic channel. A 2.5 Gbits/s secure message masked by the chaotic optical secure channel and a 10 Gbits/s message sequence carried by the conventional fiber-optic channel can be realized simultaneously when the channel spacing is 0.8 nm. The results show that the Q-factors of the recovered messages can be increased significantly whe… Show more

“…Up to now, many simulation and experimental results are reported in the aspect of long-haul transmission and wavelength division multiplexing, etc. [4][5][6][7][8][9][10][11][12][13][14]. Nowadays, optical fibers are substituting the copper cables progressively in the access network area, which brings a worldwide acceleration of the passive optical networks (PON) [15].…”

“…At the receiver, the message can be filtered out by the receiver laser, and the chaotic carrier that synchronizes with the carrier generated by the transmitter can be obtained. Then, the message can be decrypted by subtracting the output of the receiver laser from the encrypted signal [3,4]. With the in-depth exploring the secure chaotic optical communication, the issues for secure chaotic optical communication mainly focus on bandwidth enhancement [5], generation of novel chaotic carriers [6], chaotic photonic integrated circuits (PICs) [7], and bidirectional communications [8].…”
