We propose theoretically and demonstrate experimentally an optical architecture for flexible Ultra-Wideband pulse generation. It is based on an N-tap reconfigurable microwave photonic filter fed by a laser array by using phase inversion in a Mach-Zehnder modulator. Since a large number of positive and negative coefficients can be easily implemented, UWB pulses fitted to the FCC mask requirements can be generated. As an example, a four tap pulse generator is experimentally demonstrated which complies with the FCC regulation. The proposed pulse generator allows different pulse modulation formats since the amplitude, polarity and time delay of generated pulse is controlled.
我们从理论上提出并通过实验证明了一种用于灵活超宽带脉冲产生的光学架构。它基于一个由马赫-曾德尔调制器中的相位反转通过激光阵列馈送的N抽头可重构微波光子滤波器。由于可以轻松实现大量正负系数，因此可以生成符合FCC掩码要求的超宽带脉冲。例如，通过实验演示了一个符合FCC规定的四抽头脉冲发生器。所提出的脉冲发生器允许不同的脉冲调制格式，因为所产生脉冲的幅度、极性和时间延迟是可控的。
