Abstract

In this contribution we report on radio-frequency and in particular time-domain studies to develop a better understanding of mode-locked quantum dot (QD) two-section lasers emitting at 1.3 μm. Based on substantial investigations of the optical pulsewidth evolution showing pulsewidths well below 4 ps, we will present the measured dependences of the optical pulsewidth as well as the pulse-to-pulse timing jitter on gain current, absorber bias voltage and RF power. Based on these results we will discuss the shortening of the pulsewidth, the corresponding RF spectra evolution as well as the pulse-to-pulse rms timing-jitter evolution within a selected range of operating parameters.
