Abstract
The polarisation dynamics of vertical cavity surface emitting lasers (VCSELs) in the bistable regime is well described by Kramers theory for noise induced transitions. By employing feedback, a memory mechanism can be introduced, which make the dynamics of the system non-Markovian. Here we analyse theoretically and experimentally the residence time distribution of the bistable systems in the presence of noise and time-delayed feedback, using an opto-electronic feedback cycle for a VCSEL. We demonstrate and explain various non-exponential features of the residence time distribution using a continuous as well as a two-state model. Additionally we compare the results to an electronic Schmitt trigger, which represents an experimental realization of the two-state model.
