摘　　要：在光子辅助的W波段通信系统中,利用概率整形技术,实验验证了概率整形的八进制脉冲幅度调制(PS-PAM8)信号在太赫兹空芯光纤中的有线传输。采用包络检测的方案,在97~105 GHz的W波段上成功实现了5.75 GBaud的PS-PAM8信号在1 m空芯光纤上的传输。实验中的净传输速率可达13.63 Gbit/s,满足2.4×10^(-2)的20%开销的软判决前向纠错码阈值。该实验结果证明了THz空芯光纤作为一种新型的W波段高速传输介质的潜力。We experimentally verified the wired transmission of the probabilistically shaped 8-level pulse amplitude modulation(PS-PAM8) signal over terahertz hollow-core fibers in a photonic-aided W-band communication system by using the probabilistic shaping technology.Via the envelope detection scheme,we carried out the transmission of the 5.75-GBaud PS-PAM8 signal over 1-m hollow-core fibers at the W-band from 97 GHz to 105 GHz.The net transmission rate in the experiment reaches 13.63 Gbit/s,which is within the soft-decision forward error correction threshold of 2.4×10^(-2) with a 20% overhead.The experimental results prove the potentiality of THz hollow-core fibers to be a new high-speed W-band transmission medium.
