Delayed feedback control of localized states in a broad area vertical cavity surface emitting laser with saturable absorber

We are interested in spatio-temporal dynamics of localized states in a transverse section of a broad area vertical cavity surface emitting laser (VCSEL) with saturable absorbtion subjected to time-delayed optical feedback. It can be shown that variation of feedback parameters leads to a multistability of stationary solutions that is caused by a phase bifurcation. In addition, we demonstrate that the presence of the delayed optical feedback can induce Andronov-Hopf bifurcation and a period doubling route to chaos. Moreover, a coupling between this bifurcation scenario with aforementioned delay-induced multistability causes complex spatio-temporal behavior of the system in question.
