A new programmable optical chip lets engineers slow light on demand. This capability gives far greater control over how optical signals propagate within a circuit.
The technology matters for high-speed computing and data communication. By tuning the propagation rate of light, devices can process and synchronize signals with greater precision — a foundation for next-generation networks and data centers.
Advances in photonics like this could reshape how digital infrastructure is built, including the high-speed networks that underpin modern services.
