| 摘 要： | 基于两个级联偏振调制器，提出了一种高频谱纯度、稳定的六倍频微波信号产生方法。该方法通过适当调整偏振片的偏振方向、射频驱动信号电压和相位，实现无光滤波器条件下、任何波段六倍频微波信号的产生。利用Optisystem平台搭建的仿真系统，以S波段4 GHz信号为例，验证了该设计系统产生的六倍频信号质量，并分析了非理想射频驱动电压和相位对六倍频信号质量的影响，结果表明:该设计系统能产生最大光边带抑制比、射频无杂散抑制比分别为21.3，15.2 dB的六倍频微波信号；且非理想驱动电压和相位差的偏离应控制在理想值5%的范围之内。

| Abstract: | Based on two cascaded polarization modulators, a stable frequency-sextupled microwave signal generation approach with high spectral purity is presented. Without optical filter, a frequency-sextupled microwave signal of any wave-band was obtained by adjusting the direction of polarizers, the voltage and the phases of radio frequency driven signals. A simulation system was set up based on an OptiSystem platform, and the quality of the generated frequency-sextupled signal, using 4 GHz signal as an example, was verified. Further, the influences of non-ideal radio frequency driven voltage and phases on the quality of the generated frequency-sextupled signal were analyzed as well. The results show that the designed system can generate frequency-sextupled signal with maximum optical sideband suppression ratio and radio frequency spurious suppression ratio of 21.3 dB, 15.2 dB, respectively. In order to obtain the higher quality microwave signal, the non-ideal deviations from ideal driven voltage and phase difference should be controlled within 5%. |
