标题： Frequency-Division Phase Random Optimization for High-Speed Arbitrary Optical Intensity Waveform Monitoring Using Opto-Electronic Finite Impulse Response Filters

摘要： 我们提出并演示了一种基于频分相位随机优化（FD-PRO）的高带宽光强度波形监测技术，该技术使用光电有限脉冲响应（OE-FIR）滤波器。 在此技术中，相位随机优化（PRO）使信号谱相位的估计成为可能。 频分分析（FDA）结合PRO节省了优化所需的迭代，加快了信号谱相位的估计。 FDA还促进了信号谱幅度的估计。 使用FD-PRO，可以轻松重建任意光强度波形，而无需依赖高速数字信号处理。 实验结果表明，在18-ps分辨率下，时间波形成功被重建。 显示英文摘要

摘要： We propose and demonstrate a high-bandwidth optical intensity waveform monitoring technique based on frequency-division phase random optimization (FD-PRO) using an opto-electronic finite impulse response (OE-FIR) filter. In this technology, phase random optimization (PRO) enable the estimation of the signal spectral phase. Frequency-division analysis (FDA) combined with PRO saves the iteration required for the optimization, accelerating the signal spectral phase estimation. FDA also facilitates the estimation of the signal spectral amplitude. Using FD-PRO, arbitrary optical intensity waveforms can be easily reconstructed without relying on high-speed digital signal processing. Experimental results reveal that the temporal waveforms are successfully reconstructed at 18-ps resolution.
