提出了一种基于超结构光纤光栅(SSFBG)脉冲整形产生毫米波脉冲信号的新方法。该方案首先将输入的皮秒高斯脉冲经过SSFBG整形后转化为n个高斯脉冲,然后利用线性啁啾光纤布拉格光栅(LCFBG)或其他高色散元件对脉冲串进行复制,形成所需的调频毫米波光脉冲包络。高速光电探测器(PD)和带通滤波器可以将毫米波光脉冲最终转换为毫米波脉冲信号。根据这种方案,可以很容易地产生频率高达10GHz的毫米波信号的完成的光纤组件。
A novel optical approach is proposed to generate millimeter wave (MMW) pulse signal based on the pulse reshaping of superstructure fiber Bragg grating (SSFBG). In our scheme, one input pico-second Gaussian pulse is transformed into n Gaussian pulses by the SSFBG reshaping firstly, and then the pulse train is replicated to form a required frequency modulation MMW optical pulse envelope by the linear chirped fiber Bragg grating (LCFBG) or other highly dispersive element. The high-speed photodetector (PD) and band-pass filter can transform the MMW optical pulse into an MMW pulse signal ultimately. Depending on this scheme, MMW signals with frequency up to 10GHz can be easily generated by the completed fiber components.
