| Abstract: | We report on experimental observations of dual-wavelength solitons in a passively mode-locked erbium-doped fiber laser. Two kinds of dual-wavelength solitons with different spectrum shapes are achieved. One is exhibited to have spectrum sidebands and the other one is shown to have the smooth profile without any sideband. The mode-locking mechanism at different central wavelengths is analyzed. Experimental results suggest that the pump level together with the cavity filtering effect play key roles in the generation of the dual-wavelength solitons. |
