Abstract:

In this paper, we propose a novel carrier-less amplitude/phase modulation with probabilistic shaping based on the Lorenz model and superposition method (LS-PS-CAP). The chaotic model is used to change the probability distribution of the constellation, and superimpose the constellations to obtain LS-PS-16CAP. The proposed scheme can increase modulation flexibility and improve BER performance, and it can also provide security for the transmission system. The transmission of 189.6 Gb/s LS-PS-16CAP data signal over a 2.5 km multi-core fiber (MCF) is experimentally demonstrated. Moreover, the LS-PS-16CAP obtains an average gain of 0.7 dB with the entropy of 3.7bits/symbol compared to the Maxwell-Boltzmann (MB)-PS-16CAP in MCF. The findings suggest that the proposed scheme has a promising future for short-range optical transmission system.
