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 paper concludes with the successful experimental demonstration of an IM/DD optical subsystem that simultaneously uses four distinct states of polarization for transmitting four independent data streams, achieving transmission below the forward error correction limit over 2-km SSMF.
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 polarization change conditions.
