【摘要】：利用光克尔效应和交叉相位调制效应,采用基于矩阵的主元素广义投影(PCGP)算法,提出了基于克尔晶体的频率分辨光学开关法(FROG)光学任意波形测量方案。建立了基于克尔晶体的FROG光学任意波形测量的理论模型,并对该方案进行了仿真研究,讨论背景噪声处理、门函数形状、门波形幅度对波形恢复的影响。仿真结果表明:该方案可以实现对光学任意波形的幅度和相位的准确测量;门脉冲采用矩形波形时,光学任意波形的测量准确性较高。

[Abstract]:Using the optical Kerr effect and the cross-phase modulation effect, a matrix-based main element generalized projection (PCGP) algorithm is used, and an arbitrary waveform measurement scheme based on a Kerr-crystal-based frequency-resolved optical switching method (FROG) is proposed. The theoretical model of arbitrary waveform measurement of the FROG based on the Kerr crystal is established, and the simulation research of the scheme is carried out, and the influence of the background noise processing, the shape of the gate function and the amplitude of the gate waveform on the waveform recovery is discussed. The simulation results show that the scheme can measure the amplitude and phase of any arbitrary waveform, and when the gate pulse adopts the rectangular waveform, the measurement accuracy of the optical arbitrary waveform is high.
