提出了一种基于单阵列FBG（光纤布拉格光栅）的任意波形产生装置。该装置包括光学频率梳产生部分和脉冲整形部分。在光学频率梳产生部分，利用自相位调制效应压缩拍频光得到光学频率梳；脉冲整形部分包括FBG阵列、偏振控制器、光纤拉伸器和偏振片。不同波长的谱线经过不同数量的偏振控制器后其偏振态各不相同，经过偏振片后各条谱线的幅度会发生不同程度的衰减。相位控制器通过改变光纤的长度改变谱线的相位。通过该结构进行实验并仿真，得到了频率为125 GHz的类似三角波和高斯波的波形。

In this paper, a single array FBGbased Optical Arbitrary Waveform Generation (OAWG) system is proposed, which consists of two parts: optical frequency combs generation and pulse shaping. The former is obtained by compressing a dual wavelength beat light using the SelfPhase Modulation (SPM) effect and the latter composed of FBG array, polarization controllers (PC), Fiber Stretchers (FS) and a polarizer. The polarization states of the spectral lines at different wavelengths are different after passing through different number of PC and the amplitude of each line attenuates to a different extent after passing through the polarizer. The phase controllers adjust the phase of each spectral line by manipulating the length of the fiber. Using this system in experiments and simulation, we obtain waveforms with a frequency of 125 GHz similar to triangular and Gaussian waves.
