基于受激布里渊散射效应和相位调制技术,实现了可调谐单通带微波光子滤波.单泵浦信号时,滤波器的频率调谐范围为0.5GHz~18.3GHz.采用一个激光器,通过外加在强度调制器上的微波信号强度调制得到泵浦信号时,滤波系统的稳定性优于两个激光器分别作光载波和泵浦信号的系统.当采用频率间隔为布里渊频移两倍的双泵浦信号时,滤波器的频率调谐范围为0.9GHz~31.3GHz. |

A tunable single-passband microwave optical filter is realized based on the stimulated Brillouin scattering and phase modulation.When only one pump signal is introduced,the tuning range of the filter is 0.5 to 18.3GHz.When only one laser is used,and pump signal is achieved by intensity modulation of the microwave signal added at intensity modulator,the stability of the filter system is better than that of the system whose two lasers are used as light carrier and pump signal respectively.When introducing two pump signals whose frequency interval equals the two times as large as the stimulated Brillouin frequency shift,the tuning range of the filter is 0.9 to 31.3GHz. |
