Propose a technology of RoF frequency up-conversion without local oscillator based on optical injection into FP-LD. Using this technology which is based on Non-linear Dynamics System, can do RoF frequency up-conversion for NRZ-OOK, RZ-OOK signal light without local oscillator. 提出了一种基于光注入FP-LD的无本振RoF上变频技术,利用光注入FP-LD所具有的非线性动力学特性,即可对NRZ-OOK、RZ-OOK信号光进行无本振RoF上变频。
