Summary

• What is new: Introduces a novel photonic next-generation reservoir computer (NG-RC) that bypasses limitations of prior models by avoiding the need for a nonlinear physical cavity.
• Why this is important: Existing photonic RCs are hampered by limited control over memory structures and long warm-up times due to reliance on a nonlinear physical cavity.
• What the research proposes: A new photonic NG-RC using a fiber optic platform to generate feature vectors from nonlinear combinations of input data with varying delays, utilizing Rayleigh backscattering for output.
• Results: Achieved state-of-the-art performance on observer tasks with systems like Rössler, Lorenz, and Kuramoto-Sivashinsky, demonstrating scalability, low latency, and low power consumption.
