Abstract

We report the simultaneous generation of conventional soliton (CS) and dissipative soliton (DS) in a mode-locked fiber laser exploiting chirped fiber Bragg grating and four-port circulator. The bandwidth and duration of the CS are 0.28 nm and 15.1 ps, respectively. However, the giant-chirp DS exhibits a quasi-rectangular spectrum with a bandwidth of 9.5 nm. The duration of the output DS is 7.3 ps and can be compressed to 0.55 ps external to the cavity. Our numerical results agree well with the experimental observations. The flexible all-fiber laser can provide three different pulse sources, which is convenient and attractive for practical applications.
