摘要： The present disclosure provides a photonics-aided vector terahertz signal communication system. The system includes an optical frequency comb generation module, a vector terahertz signal generation module, an optical fiber transmission module, a vector terahertz signal detection module, and a vector terahertz signal emission module that are sequentially connected, where the vector terahertz signal generation module includes a first binary sequence generator, a first electronic amplifier, and a first intensity modulator that are sequentially connected, the first binary sequence generator generates binary data representing to-be-transmitted data, the first intensity modulator performs, based on the binary data, amplitude modulation on an optical frequency comb entering the first intensity modulator, and an optical signal obtained after the modulation of the first intensity modulator is a vector terahertz signal carrying the to-be-transmitted data. In the present disclosure, a vector terahertz signal can be generated by using an intensity modulator.
