A physical security-enhanced wavelength division multiplexed passive optical network (WDM-PON) based on chaos synchronization between twin laser pairs is introduced. Differing from the conventional WDM-PON systems, the downstream and upstream data are physically encrypted by chaotic carriers, and the decryption processes are performed based on WDM chaos synchronization. We numerically demonstrate that with sufficient wavelength spacing, a high quality chaos synchronization between the chaotic carriers with identical wavelength can be maintained, which enables the proposed WDM-PON to afford multichannel chaotic communications at high bit rates in both the downstream and upstream directions; in addition, the security of the physical layer can be greatly enhanced. The proposed scheme shows a potential way for implementing physically-secure PONs.
