A photonic approach that can generate triangular and rectangular waveforms is proposed.A dual-electrode Mach-Zehnder modulator(De-MZM)is used to fulfill the external optical carrier suppression(OCS)modulation of a continuous wave(CW).The follow-up four-wave mixing(FWM)in a semiconductor optical amplifier(SOA)makes four primary sidebands exist in the spectrum.Then filtering and optical carrier recovery techniques are used to con-struct the spectrum aligning with that of a triangular/rectangular waveform.In this work,we also elaborate the influ-ence of errors of key device parameters,by which the feasibility and stability of the system have been verified.Based on this photonic approach,a 10 GHz full-duty-cycle triangular waveform and a 50％-duty-cycle rectangular waveform are successfully obtained.This approach provides a feasible method to generate multiple waveforms.
