We propose and experimentally demonstrate a novel and simple tunable passively mode-locked fiber ring laser. A polarization-dependent Mach-Zehnder amplitude modulator is used to replace the polarizer inside the cavity. When the modulator is biased at different voltages and without any rf input signal, we obtain a stable soliton pulse train with repetition rates from 50 to 300 GHz.
