Abstract
High-repetition rate (20 GHz), wavelength tunable (40 nm) optical puls es have been generated by gain switching of 1.55-mu m Fabry-Perot (FP) multiple-quantum-well (MQW) lasers using continuous-wave (CW) light i njection for longitudinal mode. selection, After fiber compression, a pulse duration shorter than 5.8 ps was obtained over the entire wavele ngth tuning range, The pulsewidth, chirping characteristics and side-m ode suppression ratio were investigated as functions of the seeding po wer and wavelength. In addition, we report on the observation of chaos and period doubling for a gain-switched laser without injection seedi ng, and show that irregular behavior can be suppressed by injection se eding of the laser.
