Monolithic self-mode-locked (SML) semiconductor lasers (SCLs) based on Quantum Dashs (QDh) offer stable and broad optical mode combs with mode spacings in the Multi-GHz range. In this contribution, we investigate experimentally the impact of time-delayed optical self-feedback (OFB) on the comb spacing tunability of a single-section QDh comb laser. The influence of varying optical feedback strengths and optical feedback delays is validated experimentally and by adapting a stochastic time-domain model.
