  • 摘要:

    提出一种倍频因子连续可调,且相位连续变化的微波光子移相系统。该方案使用两个并联的马赫曾德尔调制器,通过2×2光耦器与两个双并联的集成马赫曾德尔调制器级联,产生可调节的±1~4阶边带,并使用相位调制器对其中一个光波进行相移。通过调整DPMZM的射频驱动信号和直流偏置电压以及PM的直流电压,可以产生相位从0到360°连续可调的2到8次谐波。仿真结果表明,当射频信号频率为10 GHz时,可产生频率为20~80 GHz的微波信号。当相位调制器的直流偏置电压与半波电压比值在0到2间变化时,对应微波信号的相位从0°到360°变化,可以获得约20 dB的大光边带抑制比(OSSR)和电杂散抑制比(ESSR)。此外,分析了调制器消光比对输出微波信号光载波抑制比和电杂散抑制比的影响,以及光载波的波长和功率对微波信号幅度波动的影响。
