Multiple delay nonlinear wavelength dynamics for photonic Reservoir Computing

International audienceReservoir computing is an emerging field of research intended to develop novel computational machines based on operating principles issued from the neural network community and the brain research sciences. Practical implementations of the corresponding principles is a strongly open question, which is precisely addressed from the photonic viewpoint in the frame of a recently funded EC project PHOCUS. The main idea is here to benefit from the intrinsic dynamic complexity of delay systems, which experimental realization are well known in photonics, in order to perform the central role of a reservoir computer, the reservoir itself. This paper reports on the photonic implementation, the numerical simulations of the corresponding reservoir subjected to the NARMA sequences, and the computational power results that were obtained both numerically and experimentally
