An experimental investigation of a semiconductor laser subject to moderate to strong optical feedback shows that sporadic power discontinuities occur everywhere along the boundary separating feedback regimes IV and V. These low-frequency fluctuations (LFF’s) do not occur just near the solitary-laser threshold as previously thought. Furthermore, although the LFF’s appear as power dropouts near threshold, they manifest as power jump-ups well above threshold. Theoretical modeling shows reasonable agreement with experiments.
