abstract = {We investigate theoretically the impact of optical feedback on
quantum dot two-color laser dynamics when emitting from both the
excited and the ground states. Detailed analysis of the laser
dynamics is provided by numerical integrations and continuation
techniques, as well as by analytical methods. As the feedback
strength is increased the quantum dot laser undergoes a sequence
of bifurcations involving steady-states, external cavity modes,
self-pulsations and chaos. Furthermore, we report on two
interesting mode competition results. First, the optical feedback
favors the ground state emission; hence an increase of the
feedback strength will generally lead to an increase of the
ground state emission output power. Second, the optical feedback
can select one lasing state or induce bistable switchings between
different steady-states depending on the feedback strength and
the injection current.}
