Abstract

The paper presents both numerical and experimental investigations on the behavior of 1.55 micrometers distributed feedback (DFB) laser diode (LD) driven by strong RF power. The picosecond dynamic response of gain-switched DFB LD can be analyzed by appropriate rate equations. The results of experimental research are generally in good agreement with the numerical calculations and the minimum pulse width is about 17 ps under 1 GHz, 20 dBm RF modulation.
