为了对任意波形测量技术(OAWM)进行研究,利用高阶非线性光纤中交叉相位调制效应(HNL-XPM),互相关光学频率分辨光学开关法( X-FROG),提出了一种测量光学任意波形的新方案。以变换极限脉冲、线性正啁啾脉冲、双脉冲以及任意波形脉冲作为待测脉冲,采用Matlab软件对以上光脉冲光谱图进行了数值模拟,基于矩阵的主元素广义投影算法( PCGP)从数值模拟的光谱图中恢复了脉冲的振幅和相位,误差达到收敛的标准( G<10-5)。结果表明,该方案能够精确地测量任意波形脉冲。

For the sake of studying Optical Arbitrary Waveform Measurement (OAWM),a new scheme of optical arbitrary waveform measurement is proposed using higher-order nonlinear fiber cross-phase modulation effects and cross-correlation frequency-resolved op-tical gating. Then,several common optical pulses spectra are simulated by Matlab software such as transform-limited pulses,linear posi-tive chirp pulses,double pulses and arbitrary waveform pulses and use principal component generalized projects algorithm to retrieve am-plitude and phase of the pulse spectra for the free-noise XPM-XFROG traces,the error of the convergence is criteria ( G<10-5 ) . The re-sults show that this scheme can accurately measure optical arbitrary waveform pulses.
