A passively mode-locked fiber laser to generate chirp-adjustable square-wave pulses is reported. A simple chirp measurement system is designed to study the output chirp of the fiber laser. The results indicate that the chirp of the square-wave pulses in our fiber laser can be adjusted by the polarization controllers inside the cavity. Three typical chirp states, including random chirp, V-shaped chirp and linear chirp, are achieved. This kind of fiber laser cannot only help to further understand the characteristics of square-wave pulse but also serve as multifunction light source for potential applications.
