Dispersion-managed dual-wavelength fiber laser based on nonlinear polarization evolution

We report the generation of dual-wavelength dispersion-managed solitons in a near-zero anomalous-dispersion Er-doped mode-locked fiber laser. Transmissive dual channels are provided by birefringence filtering effect. The dual-wavelength mode-locking centers at 1539.1 and 1578.8 nm with the repetition-rate difference of 430 Hz. Furthermore, coexistence of the soliton and the bound state is also observed.
