In this conference contribution the response of two monolithic passively mode-locked semiconductor lasers are compared whereby one laser has a quantum-well gain material and the other laser consists of a quantum dot gain material. Both as-cleaved lasers are 3 mm long with a saturable absorber section length of 10%. The two lasers are studied in an optical self feedback set-up with an optical feedback cavity length of 5.9 m and are compared by adapting a stochastic time-domain model [Drzewietzki et al., Opt. Express 21 (2013), 16142] to predict the repetition rate tuning trends, timing jitter reduction and response to optical self feedback.
