REPORT DATE (DD-MM-YYYY)2 Optical arbitrary waveform generation using the line-by-line pulse shaping technique has been shown to be sensitive to variations in the offset frequency of the input frequency comb due to time-domain waveform interference. Here we present a frequency-domain model that is able to predict waveform changes arising from offset frequency variations. In experiments we controllably shift the frequency of a comb derived from a phase-modulated CW laser, which allows us to quantitatively investigate waveforms generated by pulse shaping as a function of offset frequency. Experimental data are in excellent agreement with the predictions of our frequency-domain model.

Spectral line-by-line pulse shaping for optical arbitrary pulse-train generation

“…The spectral line fluctuation has almost no effect on the periodicity of the generated pulse train, since the periodicity is determined by the rf driving frequency on the actively mode-locked laser, which is quite stable. However, the spectral line fluctuation introduces distortion and/or noise on the generated pulse train and waveforms [20,28]. Although in our experiments the spectral lines show sufficient stability for the OAPTG demonstration, it is highly desirable to have laser sources with improved stability, since it has been realized that stabilized spectral lines play a critical role in the spectral line-by-line pulse shaping and optical arbitrary waveform generation [29].…”

Spectral line‐by‐line shaping for optical and microwave arbitrary waveform generations

“…The impact of frequency comb instability on optical waveform generation can be apparent even for the simple case of selecting only two spectral lines with applied phase control [8]. The focus of this section is to model the impact of frequency comb stability on shaped waveforms [46]. A simple case employing only two spectral lines and independent phase control on these lines provides significant insight into the source of time-domain waveform instability.…”

Polarization line-by-line pulse shaping for the implementation of vectorial temporal Talbot effect

“…Spectral line-by-line pulse shaping, in which discrete frequency components of the laser source are independently controlled, allows optical arbitrary waveform generation (OAWG) [1][2][3][4]. In performing line-by-line pulse shaping, a laser source with a low offset frequency variation (optical frequency comb laser) becomes essential [5]. The integration of pulse shaping and an optical frequency comb allows generation of waveforms with both controllable ultrafast time structure and long term coherence.…”
