Terahertz wireless transmission enabled by photonics using binary phase-shift keying at 300 GHz

摘要

This paper presents the first real-time wireless transmission at 300 GHz using binary phase-shift keying (BPSK) modulation. A coherent transmitter based on photonics enabled an error-free transmission (bit-error rate: BER < 10) at a record data rate of 40 Gbit/s. In order to stabilize the frequency and phase of carrier signals in the transmitter, we proposed and demonstrated an active phase-stabilization technique using an optical frequency comb (OFC). Our method is applicable to more complicated modulation formats to increase the data rate of real-time terahertz communications to over 100 Gbit/s.
