Arbitrary waveform optical pulse generation using an optical pulse synthesizer

We have proposed an optical pulse synthesizer, which consists of optical modulators and an arrayed waveguide grating (AWG). This system can generate arbitrary waveform pulses in combination with broadband optical frequency comb. We achieved generation of the Gaussian pulse with a width of 5.1 ps, double-Gaussian pulse and rectangular-shaped pulse as arbitrary waveform pulse synthesis, at a high repetition rate of 10 GHz.
