While the time jitter of gain-switched multimode Fabry–Pérot lasers is relatively low, single-mode distributed feedback (DFB) lasers suffer from an inherently larger time jitter, due to the different photon statistics. Here, we determine the time jitter of a mulitmode Fabry–Pérot (FP) laser (425 fs), a single-mode DFB laser (2.2 ps), and the FP laser switched to single-mode pulsing by self-seeding (210 fs). Thus self-seeding is superior by one order of magnitude to gain switching of DFB lasers, which is presently used for generation of single-mode pulses in the low ps range. A numerical model based on multimode rate equations including Langevin terms for the spontaneous emission shows good agreement with the experimental results. © 1994 American Institute of Physics.
