Monolithic mode-locked edge-emitting semiconductor quantum dot lasers emitting at 1.31 micrometer are ideal sources for the generation of broad optical frequency combs for short-reach inter and intra data-center links. In this contribution, the emission dynamics of InAs/InGaAs quantum dot lasers with broad-ridge waveguide are studied experimentally. Our analysis focuses on spectral, radio-frequency and time-domain analysis as well as initial spectro-temporal emission properties.
