研究目的
Demonstrating an intensity-modulated direct-detection link using four states of polarization for high-capacity IM/DD optical data links.
研究成果
The study successfully demonstrates a quaternary polarization-multiplexed IM/DD system capable of transmitting four independent data streams over 2-km SSMF with below-FEC limit performance. The system's potential for simplifying receiver structures and increasing per-channel capacity is highlighted.
研究不足
The system's performance is evaluated over a short reach of 2-km SSMF, and the polarization tracking algorithm's stability is tested under stringent conditions. The study does not explore longer transmission distances or the impact of more severe polarization-dependent impairments.
