Generation of low jitter single mode ultrashort optical pulse at arbitrary repetition rate

A modified injection seeding setup, which can generate low jitter single mode picosecond optical pulses independent of the repetition rate in principle, was presented in this article. With a gain-switched DFB laser diode employed as the external injection seeding, a gain-switched Fabry–Perot laser diode can generate single mode ultrashort optical pulses with 0.76 ps jitter and 24.5 dB side-mode-suppression ratios. The time window of jitter decrease for the DFB laser injection pulses, in which the FP laser pulses are insensitive to its repetition rate, is numerically simulated and experimentally demonstrated. © 2006 Wiley Periodicals, Inc.
