We propose and numerically validate an all‐optical scheme to generate a train of optical pulses. Modulation of a continuous wave with a periodic binary temporal phase pattern followed by a spectral phase shaping enables us to obtain ultrashort pulse trains. An ideal step phase profile as well as a profile arisen from a bandwidth‐limited device is investigated. Analytical guidelines describing pulse train formation and their characteristics are provided. Pulses with a duration of a few picoseconds at a repetition rate of 10 GHz can be expected for realistic experimental conditions.

二进制时间相位调制产生超短脉冲

我们提出并在数值上验证了全光学方案以生成一系列光脉冲。用周期性的二进制时间相位模式对连续波进行调制，然后进行频谱相位整形，可以使我们获得超短脉冲序列。研究了理想的阶跃相位分布图以及由带宽受限的设备产生的分布图。提供了描述脉冲序列形成及其特性的分析指南。对于现实的实验条件，可以预期以10 GHz的重复频率持续几皮秒的脉冲。
