Abstract
Short optical pulses of duration <10 ps can be generated by either gain switching or mode locking.1 It has been reported that active mode locking produces pulses that are considerably shorter and more stable than those produced by gain-switched lasers. Timing jitters of 0.65 ps in electrically gain-switched lasers and 65 fs in actively mode-locked lasers were reported previously.2,3 Here we report that, contrary to the common belief, comparably stable pulses can also be generated by electrical gain switching.
