Forecasting Extreme Events in the Complex Dynamics of a Semiconductor Laser with Feedback
arXiv:1712.04538
Abstract
Complex systems performing spiking dynamics are widespread in Nature. They cover from earthquakes, to neurons, variable stars, social networks, or stock markets. Understanding and characterizing their dynamics is relevant in order to detect transitions, or to predict unwanted extreme events. Here we study the output intensity of a semiconductor laser with feedback, in a regime where it develops a complex spiking behavior, under an ordinal patterns analysis. We unveil that the complex dynamics presents two competing behaviors that can be distinguished with a thresholding method, and we use temporal correlations to forecast the extreme events, and transitions between dynamics.
