摘　　要：提出了相位独立可调的基于双阵列光纤布拉格光栅的任意波形光脉冲发生器,该发生器包括幅度控制器和相位控制器两部分。幅度控制器和相位控制器中的可调节元件是光纤布拉格光栅阵列。光纤布拉格光栅阵列由光纤布拉格光栅和光纤拉伸器间隔排列构成。只调节结构中的光纤拉伸器,就可控制输出信号的各个谱线的幅度和相位,从而产生任意波形的光脉冲。相位控制器中的光纤拉伸器的调节不会影响该结构对输出信号各个谱线幅度的控制,幅度控制器中的光纤拉伸器的调节会影响输出信号的各个谱线的相位,因此幅度控制器的调节要优先于相位控制器。An optical arbitrary waveform generator based on two fiber Bragg grating （FBG） arrays with independent phase control is proposed. It is composed of an amplitude controller and a phase controller. In the amplitude controller and phase controller, the controllable components are the FBG arrays. The FBG arrays comprise radial arrangement of several FBGs and fiber stretchers. The amplitude and phase of each spectral line of the output signal are controlled by only adjusting the fiber stretchers, which results in optical arbitrary waveform pulse. The amplitudes of spectral lines of the output signal are insusceptible to adjusting the fiber stretchers in the amplitude controller. Adjusting the fiber stretchers in the amplitude controller can affect the phases of spectral lines of the output signal. So the amplitude controller should precede the phase controller to be adjusted.
