Frequency modulated optical frequency comb generation in self-mode locked single section quantum dot lasers with short fabry-perot cavity lengths of 1 mm have been studied experimentally and by simulation [Weber et al., Optics Letters 44(14), pp. 3478-3481 (2019)]. Ultra short optical self-injection of optical frequency comb quantum cascade lasers has been reported to change and control the group delay dispersion of the optical frequency comb [Hillbrand et al., Optics Letters 43(8), pp. 1746-1749 (2018)]. In this contribution we study the impact of ultra-short optical self-injection onto frequency-modulated optical frequency combs in self-mode locked quantum dot lasers with respect to change in group delay dispersion and intermode-beat-frequency tuning.
