Summary

Can VCSEL spiking dynamics support prediction beyond a classification task?

Uses a single-VCSEL spiking-network architecture with temporally separated inputs that provide memory.

Demonstrates multistep prediction of a chaotic time series.

Commentary

A benchmark task does not establish general-purpose AI capability or end-to-end energy advantage.

Laser dynamics becomes the computational resource, connecting physical modelling with learning systems.
