We demonstrate a tunable mode-locked semiconductor fiber laser incorporating a nonlinear optical loop mirror and synchronized to an external optical signal at 40 GHz, 80 GHz, and 160 GHz. The laser generates sech(2) pulses as short as 2.0 ps, 1.7 ps, and 1.3 ps at 40 GHz, 80 GHz, and 160 GHz, respectively, and is tunable within the C-band. The maximum root-mean-square timing jitter of the laser is 580 fs at 40 GHz and 80 GHz.
