Fig. 4: Simulation results of synchronized dual-wavelength mode-locked solitons.
From: Synchronized multi-wavelength soliton fiber laser via intracavity group delay modulation
a Spectrum (slight blue), filter curve (black dashed), and group delay (red). b Profile of solitons (the slight blue solid and black dashed curves correspond to pulses before and after the PPS). c, d Spectral (upper panel) and temporal (lower panel) evolutions of soliton versus roundtrips and cavity position, respectively.
