Faster High-Capacity Internet Networks Via Photonics

EU Scientists are harnessing next-generation lasers to create light-speed broadband connections and to remove the data bottlenecks that could cause the internet to grind to a halt as demand increases.

The EU-funded researchers from nine countries (Italy, Spain, The Netherlands, Finland, Germany, Israel, France, Japan, and South Korea) and 14 different organizations, call themselves PASSION — Photonic technologies for progrAmmable transmission and switching modular systems based on Scalable Spectrum/space aggregation for future agIle high-capacity metrO Networks.

The researchers are using vertical-cavity surface-emitting laser (VCSEL) sources with photonic integrated circuits, optical switches, and semiconductor optical amplifiers to develop long-wavelength, high-capacity communications. This could pave the way for light-speed metropolitan connectivity and power new smart services like future gaming and on-demand TV.
