摘要

我们提出了4D调制与定向检测采用一种新的Stokes-Vector Kramers-Kronig收发器。结果表明，采用Stokes矢量接收机、发射数字载波和Kramers-Kronig检测，可以在不使用接收机本振的情况下，有效地实现极化复用复杂双边带信号的去旋转。实验研究了载波与信号功率比、数字载波保护带、过采样比和实际MIMO等系统参数和配置的影响。最后，在60 Gbaud的PDM-16QAM单载波实验中，以低于2.0 × 10-2阈值的误码率，在80 km SSMF上实现了创纪录的480 Gb/s数据速率

Single wavelength 480 Gb/s direct detection over 80km SSMF enabled by Stokes Vector Kramers Kronig transceiver

We propose 4D modulation with directed detection employing a novel Stokes-Vector Kramers-Kronig transceiver. It shows that employing Stokes vector receiver, transmitted digital carrier and Kramers-Kronig detection offers an effective way to de-rotate polarization multiplexed complex double side band signal without using a local oscillator at receiver. The impact of system parameters and configurations including carrier-to-signal-power ratio, guard band of the digital carrier, oversampling ratio and real MIMO is experimentally investigated. Finally, a record 480 Gb/s data rate over 80 km SSMF is achieved in a 60 Gbaud PDM-16QAM single carrier experiment with a BER below the threshold of 2.0x10-2
