a–c are the output of the EDF, PC, and OIM ports in the initial stage respectively. Sub-pulses have a cyclical evolution in the cavity, which is asynchronous with the soliton. EDF erbium-doped fiber, PC polarization controller, OIM optical integrated module. d–f are 12 consecutive spectra in the spectral beating phase for the EDF port, PC port, and OIM port respectively. The spectral beating process is obvious but irregular and soliton in different ports are at different beating states. g The reconstituted spectra show a regular beating process and many other details. h The intensity evolution process at the central wavelength position, is approximately a sinusoidal evolution process with a period of about 3.33 RTs. The green, blue, and orange dots represent the outputs of the EDF, PC, and OIM ports, respectively.
