Paper Abstract

The origin of Low Frequency Fluctuations (LFF), occurring for semiconductor lasers with delayed optical feedback from an external mirror, has been intensively discussed within the last ten years. One of the key questions has been whether the LFF are a deterministic or a noise induced phenomenon. We present experimental evidence for a deterministic mechanism by demonstrating the two major predictions of this model: irregular pulsing of the intensity on picosecond timescales underlying the LFF dynamics, and the existence of stable compound cavity modes with high gain within the LFF regime. We present a systematic investigation of the dynamical regimes with respect to both, feedback rate and injection current. We demonstrate that stable emission can indeed be achieved for a wide parameter range within the LFF regime.
