The programmable envelope shaping technique of high-repetition-rate optical pulse sequences with low-speed modulation is summarized in this letter. First, we reviewed our work on amplitude-only modulation approach for generating symmetric envelopes, including parabolic, step-like and binary patterns. Next, we reported our recent demonstration of asymmetric-enveloped pulse generation achieved by applying simultaneous amplitude and phase modulations. The asymmetric patterns we demonstrated include a trapezoid envelope and a random optical pattern. Finally, we analyze the influence of practical issues of the implementation on the generated optical pulse trains through numerical simulation. The newly proposed scheme provides flexibility in envelope processing and enriches the diversity of temporal pulse shapes.

光脉冲串时间波形处理的可编程方案

本文总结了具有低速调制的高重复率光脉冲序列的可编程包络整形技术。首先，我们回顾了我们在生成对称包络（包括抛物线、阶梯状和二进制模式）的仅幅度调制方法方面的工作。接下来，我们报告了我们最近通过应用同步幅度和相位调制实现的非对称包络脉冲生成的演示。我们展示的不对称图案包括梯形包络和随机光学图案。最后，我们通过数值模拟分析了实施中的实际问题对生成的光脉冲序列的影响。新提出的方案在包络处理中提供了灵活性，并丰富了时间脉冲形状的多样性。
