摘　　要：采用双平行偏振调制器,在不使用任何光或电滤波器的条件下,利用倍频操作在双平行偏振调制器和混合器工作频段内产生相位编码信号。在10Gb/s的编码速率下,仿真实验实现了10~40GHz范围的调谐,结果表明,在光生频率内该相位编码微波信号具有良好的大范围可调谐性能。The paper proposes a photonic approach for the generation of a widely tunable arbitrarily phase-coded microwave signal based on a dual-parallel polarization modulator without using any optical or electrical filter. The inherent frequency doubling operation can make the system work at a frequency beyond the operation bandwidth of the dual-parallel polarization modulator and the hybrid. An experiment is performed, the generation of phase-coded signals tuning from 10 to 40 GHz with up to 10Gb/s coding rates is verified, and good frequency tunability is realized.
