TLDR
In this article, the authors experimentally and numerically study the dynamics of semiconductor ring lasers that are subjected to long delay and moderate self-feedback, and study the appearance and parameter dependence of low frequency fluctuations in these systems.Abstract:
In this paper, we experimentally and numerically study the dynamics of semiconductor ring lasers that are subjected to long delay and moderate self-feedback. Through varying the pump current or the feedback strength or both, we study the appearance and parameter dependence of low frequency fluctuations in these systems. In particular, we observe different routes to the building up of the initial power amplitude.read more
