Paper Abstract

We describe a novel technique for actively mode-locking laser pulses with a repetition rate ranging between 3-5 GHz. The pulses generated are nearly transformed limited with a pulse width of 72ps. In our experiment, a synthesized sweep generator drove a pigtailed laser diode with a bandwidth of 2.5 GHz with a center frequency that was tunable between 6 and 13 GHz. The frequency span of the sweep was 2.5 GHz, which is exactly equal to the axial mode spacing of the laser diode. Active mode-locking of the laser was achieved with a start and end sweep frequency of 4740 MHz and 20 GHz, respectively. We found the mode-locked pulses to be highly stable with a repetition rate that is tunable. Tunability was accomplished by keeping the center frequency and span fixed at 11.87 GHz and 14.26 GHz, and tuning the start and end sweep frequencies over a range of 5GHz to 20GHz.
