Prediction performance of reservoir computing systems based on diode-pumped Erbium doped microchip laser subject to optical delayed feedback

Abstract : Reservoir computing (RC) systems are computational tools for information processing which can be fully implemented in optics. Here, we experimentally and numerically show that an optically pumped laser subject to optical delayed feedback can yield similar results as those obtained for electrically pumped lasers. Unlike the previous implementations, the input data is injected at a time interval which is much larger than the time-delay feedback. This data is directly coupled to the feedback light beam. Our results illustrate new possible avenues for RC implementations for prediction tasks.
