摘要

我们实验演示了200 GHz下的多通道太赫兹无线信号的光子产生，数据速率高达40 Gb/s QPSK调制格式，采用光外差技术和数字相干检测。误码率测量分别对三个以5gbaud QPSK调制的子载波或两个以10gbaud QPSK调制的子载波进行，总速度分别为30gb /s或40gb /s。该系统通过使用频谱效率高的子载波信道提供高速无线传输能力，提高了整体传输速度，降低了对电子带宽的要求。

Multichannel 200GHz 40Gb/s wireless communication system using photonic signal generation

We experimentally demonstrate photonic generation of a multichannel THz wireless signal at 200 GHz, with data rate up to 40 Gb/s QPSK modulation format using an optical heterodyne technique and digital coherent detection. The BER measurements were carried out for three subcarriers each modulated with 5 Gbaud QPSK or for two subcarriers modulated with 10 Gbaud QPSK, giving a total speed of 30 Gb/s or 40 Gb/s, respectively. The proposed system can provide a high-speed wireless transmission capability by using spectrally efficient subcarrier channels that increase the overall speed and reduce the requirement for electronic bandwidth.
