摘　　要：Recently,wireless communication capacity has been witnessing unprecedented growth.Benefits from the optoelectronic components with large bandwidth,photonics-assisted terahertz(THz)communication links have been extensively developed to accommodate the upcoming wireless transmission with a high data rate.However,limited by the available signalto-noise ratio and THz component bandwidth,single-lane transmission of beyond 100 Gbit/s data rate using a single pair of THz transceivers is still very challenging.In this study,a multicarrier THz photonic wireless communication link in the 300 GHz band is proposed and experimentally demonstrated.Enabled by subcarrier multiplexing,spectrally efficient modulation format,well-tailored digital signal processing routine,and broadband THz transceivers,a line rate of 72 Gbit/s over a wireless distance of 30 m is successfully demonstrated,resulting in a total net transmission capacity of up to 202.5 Gbit/s.The single-lane transmission of beyond 200 Gbit/s overall data rate with a single pair of transceivers at 300 GHz is considered a significant step toward a viable photonics-assisted solution for the next-generation information and communication technology (ICT) infrastructure.
