提出了一种基于光子学的高速任意波形产生方法。它基于产生高速短光脉冲样本和用于幅度加权和对光学样本进行时间延迟的光栅和延迟结构。为了增加采样量，提出了一种新的延迟-衰减-耦合处理方法，以实现高分辨率的波形产生。实验结果表明，该方法产生的锯齿波具有10%的周期下降时间和1%的波形线性度偏差，具有较高的分辨率和宽带性能。
A new photonics-based method for high-speed arbitrary waveform generation is presented. It is based on generating high-speed short optical pulse samples and a grating and delay structure for amplitude weighting and time delaying the optical samples. In order to increase the number of samples, a novel delay-attenuation-coupling processing method is presented for realizing high resolution in waveform generation. Results are given for sawtooth waveform generation with fast fall time of 10% of period and waveform linearity deviation of 1%, demonstrating the high resolution and wide-band capabilities of this technique.
