介绍了一种基于受激布里渊散射的具有调谐和整形能力的高Q因子光子微波滤波器。滤波器的带通可以连续调谐，改变用于产生泵浦功率的微波振荡器，并且可以通过调制微波音调来修改滤波器的形状。通过使用单边带抑制载波调制，可以获得微波频谱上的单带通。实验结果表明，该滤波器具有较宽的调谐范围和整形能力，Q值为670。
A high Q-factor photonic microwave filter showing tuning and reshaping capabilities and based on stimulated Brillouin scattering is demonstrated. The filter bandpass can be continuously tuned, changing the microwave oscillator used to generate the pump power, and the filter shape can be modified by modulating the microwave tone. A single bandpass over the microwave spectrum can be obtained by using single-sideband suppressed carrier modulation. Experimental results demonstrate the wide tuning range of the filter, its reshaping capability, and Q factor of 670.
