基于PolM的微波光子线性优化链路
A linearly optimized microwave photonic link based on PolM
摘要
Abstract
A scheme to improve the spurious-free dynamic range(SFDR)of the system by polarization modulator(PolM)is proposed and it has been verified by simulation.In the microwave photonic link,the principle of linear optimization is to completely suppress the optical carrier in upper branch and partially suppress the optical carriers in the lower branch in the microwave photonic link,so that the generated third-order intermodulation distortion(IMD3)from different sources can be self-cancelled in the electrical domain.The simulation results show that the rejection ratio of IMD3 can reach 61.9 dB,and the third-order SFDR can reach 107 dB·Hz2/3.The proposed scheme has the advantages of simple structure,low implementation difficulty,large bandwidth and large SFDR,and has great application potential in broadband wireless communications,radars and electronic warfare systems.关键词
