Gain switched DFB laser diode pulse source usingcontinuouswave light injection for jitter suppression and anelectroabsorption modulator for pedestal suppression

Abstract

4 ps pulses with low temporal jitter (0.6 ps) and reduced pedestal (> 25 dB extinction) have been generated from a 1548 nm gain switched distributed feedback laser diode (DFB) pulse source at 2.5 GHz using continuous wave (CW) light injection for jitter suppression and an electroabsorption modulator (EAM) for pedestal suppression.
