摘　　要：设计了双光源、基于光外差法的光生微波系统,利用光通信系统设计软件OptiSystem进行了仿真。将1549.9 nm和1550.1 nm的两束光耦合后在光电探测器上拍频获得24.5 GHz的高频微波信号,实现了5G移动通信中24.25~52.0 GHz的高频毫米波信号产生方法,为5G通信中高频信源的产生进行了有效的探索。同时基于OptiSystem仿真了光纤的四波混频效应,将波长间隔0.2 nm的两束稳定频差的单纵模光波耦合并经50 km的光纤传输后,在光谱仪上清晰可见四束光,验证了光纤的色散非线性特性,为5G高频信号的传输进行了仿真研究。A photo-generated microwave system based on the optical heterodyne method with dual light sources was designed and then simulated by the design software for the optical communication system,OptiSystem.After coupling the two light beams of 1549.9 nm and 1550.1 nm,the microwave signal of 24.5 GHz was obtained by beating on the photodetector,which realized the high frequency millimeter wave signal generation method of 24.25~52.0 GHz in 5G mobile communication.The generation of high-frequency signal sources in 5G communication was effectively explored.At the same time,the four-wave mixing effect of the fiber was also simulated based on the OptiSystem.After coupling two single longitudinal mode light waves with a stable frequency difference with a wavelength interval of 0.2 nm and transmitting them through a 50 km fiber,the four beams were clearly visible on the spectrometer,which verified the non-linear characteristics of the dispersion of the optical fiber.The simulation study was carried out for the transmission of 5G high-frequency signals.
