Study of ultrafast holographic optical frequency comb synthesizer

我们提出了一种飞秒和皮秒时间段的超快光学任意波形合成器和分析器。超快波形是通过使用定制的无色光学合成器操纵千兆赫光学频率梳(OFC)的幅度和相位来产生的。采用双外差混频的方法对合成波形进行了频率轴分析。该系统已用于产生飞秒脉冲和合成幅移和相移复合键控信号。

We have proposed an ultrafast optical arbitrary waveform synthesizer and analyzer in femtosecond and picosecond time region. Ultrafast waveforms were generated by manipulating the amplitude and phase of a gigahertz optical frequency comb (OFC) using a customized colorless optical synthesizer. The synthesized waveform was analyzed on the frequency axis using a dual-heterodyne mixing. The proposed system has been applied to generate femtosecond pulses and to synthesize composite amplitude-shift and phase-shift keying signals.
