This paper describes short pulse generation at over 40 GHz using monolithic mode-locked lasers integrated with electroabsorption modulators. The electroabsorption modulator using strained-InGaAsP multiquantum wells provides a pulse shortening gate at a high-repetition frequency. Pulse generation around 4 ps has been realized at a repetition frequency of 43. 5 GHz. Pulse compression using a 1. 3 µm single mode fiber is performed and a 0. 87 ps pulse is obtained.
