Abstract
We investigate the self-oscillations of an induced absorber (CdS, photothermal effects) in a hybrid ring cavity. If the induced absorber is intrinsically bistable, we show that for a given set of system parameters different oscillation modes may exist depending on the initial conditions. In contrast to the behavior of an intrinsically bistable absorber, we find a bifurcation route to optical chaos if the induced absorber is not intrinsically bistable.
